We used the transfer matrix analysis toinvestigate continuous wave propagation through microrings, as wellwe considered the nonlinear switching characteristics of an opticaldevice using a double-coupler silicon ring resonator in presence ofthe Kerr nonlinearity, thus obtaining the bistability behavior of theoutput port, the drop port and also inside the silicon microringresonator.

One of the serious problems in this network is the fact that optical crosstalk is additive, and thus the aggregate effect of crosstalk over a whole AON may be more nefarious than a single point of crosstalk. As results, we note a huge degradation of the Quality of Service (QoS) in our network. For that, it is necessary to identify and monitor the impairments in whole network. In this way, this paper presents new system to identify and monitor crosstalk in AONs in real-time fashion. particular, it proposes a new technique to manage intra-crosstalk in objective to relax QoS of the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=All-optical%20networks" title="All-optical networks">All-optical networks</a>, <a href="https://publications.waset.org/search?q=optical%20crosstalk" title=" optical crosstalk"> optical crosstalk</a>, <a href="https://publications.waset.org/search?q=optical%0D%0Across-connect" title=" optical cross-connect"> optical cross-connect</a>, <a href="https://publications.waset.org/search?q=crosstalk" title=" crosstalk"> crosstalk</a>, <a href="https://publications.waset.org/search?q=monitoring%20crosstalk." title=" monitoring crosstalk."> monitoring crosstalk.</a> </p> <a href="https://publications.waset.org/10004121/monitoring-and-prediction-of-intra-crosstalk-in-all-optical-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10004121/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10004121/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10004121/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10004121/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10004121/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10004121/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10004121/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10004121/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10004121/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10004121/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10004121.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1718</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">627</span> Characterization Non-Deterministic of Optical Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=V.%20A.%20C.%20Vale">V.

When it matches a configured code-word, the delayed burst is switched to a set of output ports.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Optical%20multicast" title="Optical multicast">Optical multicast</a>, <a href="https://publications.waset.org/search?q=optical%20burst%20switching%20networks" title=" optical burst switching networks"> optical burst switching networks</a>, <a href="https://publications.waset.org/search?q=optical%20code-words" title=" optical code-words"> optical code-words</a>, <a href="https://publications.waset.org/search?q=tunable%20decoder" title=" tunable decoder"> tunable decoder</a>, <a href="https://publications.waset.org/search?q=virtual%20optical%20memory." title=" virtual optical memory."> virtual optical memory.</a> </p> <a href="https://publications.waset.org/9998597/optical-multicast-over-obs-networks-an-approach-based-on-code-words-and-tunable-decoders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9998597/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9998597/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9998597/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9998597/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9998597/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9998597/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9998597/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9998597/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9998597/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9998597/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9998597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1760</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">624</span> All-Optical Function Based on Self-Similar Spectral Broadening for 2R Regeneration in High-Bit-Rate Optical Transmission Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Leila%20Graini">Leila Graini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, we demonstrate basic all-optical functions for 2R regeneration (Re-amplification and Re-shaping) based on self-similar spectral broadening in low normal dispersion and highly nonlinear fiber (ND-HNLF) to regenerate the signal through optical filtering including the transfer function characteristics, and output extinction ratio.

The incorporation of all optical wavelength convertors leads to better utilization of the network resources and hence improves the efficiency of optical networks. Wavelength convertors that can work with Dispersion Managed (DM) solitons are attractive due to their superior transmission capabilities. In this paper, wavelength conversion for dispersion managed soliton signals was demonstrated at 100 Gbps through semiconductor optical amplifier and an optical filter. The wavelength conversion was achieved for a 1550 nm input signal to1555nm output signal.

Since dense wavelength multiplexing forms the physical layer for intelligent optical networking, the roll of high speed all optical switch is important. This paper analyzes such an ultra-high speed polymer electro-optic switch. The performances of the 2x2 optical waveguide switch with rectangular, triangular and trapezoidal grating profiles on various device parameters are analyzed. The simulation result shows that trapezoidal grating is the optimized structure which has the coupling length of 81μm and switching voltage of 11V for the operating wavelength of 1550nm. The switching time for this proposed switch is 0.47 picosecond.

It is composed of a SOA-MZI with a bidirectional coupler at the output. Output signals of both bar and crossbar of the SOA-MZI is fed back to SOAs located in the arms of the Mach-Zehnder Interferometer (MZI). The injected photon-rates to the SOAs are modulated by feedback signals in order to form optical flip-flop. According to numerical analysis, Gaussian optical pulses with the energy of 15.2 fJ and 20 ps duration with the full width at half-maximum criterion, can switch the states of the SR-AOFF. Also simulation results show that the SR-AOFF has the contrast ratio of 8.5 dB between two states with the transition time of nearly 20 ps. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=All%20Optical" title="All Optical">All Optical</a>, <a href="https://publications.waset.org/search?q=Flip-Flop" title=" Flip-Flop"> Flip-Flop</a>, <a href="https://publications.waset.org/search?q=Mach-Zehnder%20Interferometer%0A%28MZI%29" title=" Mach-Zehnder Interferometer (MZI)"> Mach-Zehnder Interferometer (MZI)</a>, <a href="https://publications.waset.org/search?q=Semiconductor%20Optical%20Amplifier%20%28SOA%29." title=" Semiconductor Optical Amplifier (SOA)."> Semiconductor Optical Amplifier (SOA).</a> </p> <a href="https://publications.waset.org/4727/a-novel-single-wavelength-all-optical-flip-flop-employing-single-soa-mzi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/4727/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/4727/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/4727/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/4727/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/4727/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/4727/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/4727/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/4727/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/4727/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/4727/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/4727.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2025</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">617</span> Routing Capability and Blocking Analysis of Dynamic ROADM Optical Networks (Category - II) for Dynamic Traffic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Indumathi%20T.%20S.">Indumathi T.

Category I consists of a single large optical switch; category II is composed of a number of small optical switches aligned in parallel; and category III has a single optical switch and only one wavelength being added/dropped. In this paper, to evaluate the wavelength-routing capability of ROADMs of category-II in dynamic optical networks,the dynamic traffic models are designed based on Bernoulli, Poisson distributions for smooth and regular types of traffic. Through Analytical and Simulation results, the routing power of cat-II of ROADM networks for two traffic models are determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fully-Reconfigurable%20Optical%20Add-Drop%20Multiplexers%20%28FROADMs%29" title="Fully-Reconfigurable Optical Add-Drop Multiplexers (FROADMs)">Fully-Reconfigurable Optical Add-Drop Multiplexers (FROADMs)</a>, <a href="https://publications.waset.org/search?q=Limited%20Tunability%20in%20Reconfigurable%20Optical%20Add-Drop%20multiplexers%20%28LROADM%29" title=" Limited Tunability in Reconfigurable Optical Add-Drop multiplexers (LROADM)"> Limited Tunability in Reconfigurable Optical Add-Drop multiplexers (LROADM)</a>, <a href="https://publications.waset.org/search?q=Multiplexer%2FDe-%20Multiplexer%20%28MUX%2FDEMUX%29" title=" Multiplexer/De- Multiplexer (MUX/DEMUX)"> Multiplexer/De- Multiplexer (MUX/DEMUX)</a>, <a href="https://publications.waset.org/search?q=Reconfigurable%20Optical%20Add-Drop%20Multiplexers%20%28ROADMs%29" title=" Reconfigurable Optical Add-Drop Multiplexers (ROADMs)"> Reconfigurable Optical Add-Drop Multiplexers (ROADMs)</a>, <a href="https://publications.waset.org/search?q=Wavelength%20Division%20Multiplexing%20%28WDM%29." title=" Wavelength Division Multiplexing (WDM)."> Wavelength Division Multiplexing (WDM).</a> </p> <a href="https://publications.waset.org/5725/routing-capability-and-blocking-analysis-of-dynamic-roadm-optical-networks-category-ii-for-dynamic-traffic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5725/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5725/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5725/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5725/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5725/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5725/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5725/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5725/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5725/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5725/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5725.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1528</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">616</span> Solitons in Nonlinear Optical Lattices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Tapas%20Kumar%20Sinha">Tapas Kumar Sinha</a>, <a href="https://publications.waset.org/search?q=Joseph%20Mathew"> Joseph Mathew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on the Lagrangian for the Gross –Pitaevskii equation as derived by H.

Optical flow cannot be computed locally, since only one independent measurement is available from the image sequence at a point, while the flow velocity has two components. A second constraint is needed. The method used for finding the optical flow in this project is assuming that the apparent velocity of the brightness pattern varies smoothly almost everywhere in the image. This technique is later used in developing software for motion detection which has the capability to carry out four types of motion detection. The motion detection software presented in this project also can highlight motion region, count motion level as well as counting object numbers. Many objects such as vehicles and human from video streams can be recognized by applying optical flow technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Background%20modeling" title="Background modeling">Background modeling</a>, <a href="https://publications.waset.org/search?q=Motion%20detection" title=" Motion detection"> Motion detection</a>, <a href="https://publications.waset.org/search?q=Optical%0Aflow" title=" Optical flow"> Optical flow</a>, <a href="https://publications.waset.org/search?q=Velocity%20smoothness%20constant" title=" Velocity smoothness constant"> Velocity smoothness constant</a>, <a href="https://publications.waset.org/search?q=motion%20trajectories." title=" motion trajectories."> motion trajectories.</a> </p> <a href="https://publications.waset.org/8745/motion-detection-techniques-using-optical-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/8745/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/8745/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/8745/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/8745/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/8745/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/8745/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/8745/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/8745/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/8745/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/8745/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/8745.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">5384</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">613</span> Performance Evaluation of the OCDM/WDM Technique for Optical Packet Switches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=V.%20Eramo">V.

The output signals from AWG are coded with a binary code that given to an optical switch before it signal modulate with the carrier and transmitted to the receiver. The 16-ports encoder used 16 double pole double throw (DPDT) toggle switches to control the polarization of voltage source from +5 V to -5 V for 16 optical switches. When +5 V is given, the optical switch will give code '1' and vice versa.

This study was demonstrated with a transfer speed of 10 Gb/s to a non-return zero 231-1 pseudorandom bit sequence system. This multi-wavelength converter device can simultaneously provide three channels of output signal with the support of non-inverted and inverted conversion. We studied that an all-optical multicasting and wavelength conversion accomplishing cross gain modulation is effective in a semiconductor optical amplifier which is effective to provide an inverted conversion thus negative feedback. The relationship of received power of back to back signal and output signals with wavelength 1535 nm, 1540 nm, 1545 nm, 1550 nm, and 1555 nm with bit error rate was investigated. It was reported that the output signal wavelengths were successfully converted and modulated with a power penalty of less than 8.7 dB, which the highest is 8.6 dB while the lowest is 4.4 dB. It was proved that all-optical multicasting and wavelength conversion using an optical triode with a negative feedback by three channels at the same time at a speed of 10 Gb/s is a promising device for the new wavelength conversion technology.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Cross%20gain%20modulation" title="Cross gain modulation">Cross gain modulation</a>, <a href="https://publications.waset.org/search?q=multicasting" title=" multicasting"> multicasting</a>, <a href="https://publications.waset.org/search?q=negative%0D%0Afeedback%20optical%20amplifier" title=" negative feedback optical amplifier"> negative feedback optical amplifier</a>, <a href="https://publications.waset.org/search?q=semiconductor%20optical%20amplifier." title=" semiconductor optical amplifier."> semiconductor optical amplifier.</a> </p> <a href="https://publications.waset.org/9999905/multicasting-characteristics-of-all-optical-triode-based-on-negative-feedback-semiconductor-optical-amplifiers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9999905/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9999905/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9999905/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9999905/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9999905/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9999905/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9999905/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9999905/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9999905/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9999905/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9999905.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1928</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">607</span> Optical and Dielectric Properties of Self-Assembled 0D Hybrid Organic-Inorganic Insulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=S.%20Kassou">S.

The material has a layered structure. The optical transmittance (T %) was recorded and applied to deduce the absorption coefficient (α) and optical band gap (Eg). The hybrid shows an insulator character with a direct band gap about 4.46 eV, and presents high dielectric constants up to a frequency of about 10<sup>5</sup> Hz, which suggests a ferroelectric behavior. The reported optical and dielectric properties can help to understand the fundamental properties of perovskite materials and also to be used for optimizing or designing new devices.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Dielectric%20constants" title="Dielectric constants">Dielectric constants</a>, <a href="https://publications.waset.org/search?q=optical%20band%20gap%20%28Eg%29" title=" optical band gap (Eg)"> optical band gap (Eg)</a>, <a href="https://publications.waset.org/search?q=optical%20parameters" title=" optical parameters"> optical parameters</a>, <a href="https://publications.waset.org/search?q=Raman%20spectroscopy" title=" Raman spectroscopy"> Raman spectroscopy</a>, <a href="https://publications.waset.org/search?q=self-assembly%20organic%20inorganic%20hybrid." title=" self-assembly organic inorganic hybrid."> self-assembly organic inorganic hybrid.</a> </p> <a href="https://publications.waset.org/10006663/optical-and-dielectric-properties-of-self-assembled-0d-hybrid-organic-inorganic-insulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10006663/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10006663/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10006663/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10006663/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10006663/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10006663/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10006663/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10006663/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10006663/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10006663/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10006663.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1874</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">606</span> Study of Aero-thermal Effects with Heat Radiation in Optical Side Window</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chun-Chi%20Li">Chun-Chi Li</a>, <a href="https://publications.waset.org/search?q=Da-Wei%20Huang"> Da-Wei Huang</a>, <a href="https://publications.waset.org/search?q=Yin-Chia%20Su"> Yin-Chia Su</a>, <a href="https://publications.waset.org/search?q=Liang-Chih%20Tasi"> Liang-Chih Tasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In hypersonic environments, the aerothermal effect makes it difficult for the optical side windows of optical guided missiles to withstand high heat. This produces cracking or breaking, resulting in an inability to function. This study used computational fluid mechanics to investigate the external cooling jet conditions of optical side windows. The turbulent models k-ε and k-ω were simulated. To be in better accord with actual aerothermal environments, a thermal radiation model was added to examine suitable amounts of external coolants and the optical window problems of aero-thermodynamics. The simulation results indicate that when there are no external cooling jets, because airflow on the optical window and the tail groove produce vortices, the temperatures in these two locations reach a peak of approximately 1600 K. When the external cooling jets worked at 0.15 kg/s, the surface temperature of the optical windows dropped to approximately 280 K. When adding thermal radiation conditions, because heat flux dissipation was faster, the surface temperature of the optical windows fell from 280 K to approximately 260 K. The difference in influence of the different turbulence models k-ε and k-ω on optical window surface temperature was not significant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=aero-optical%20side%20window" title="aero-optical side window">aero-optical side window</a>, <a href="https://publications.waset.org/search?q=aerothermal%20effect" title=" aerothermal effect"> aerothermal effect</a>, <a href="https://publications.waset.org/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/search?q=hypersonic%20flow" title=" hypersonic flow"> hypersonic flow</a> </p> <a href="https://publications.waset.org/9027/study-of-aero-thermal-effects-with-heat-radiation-in-optical-side-window" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9027/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9027/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9027/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9027/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9027/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9027/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9027/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9027/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9027/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9027/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9027.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3116</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">605</span> A Framework for the Design of Green Giga Passive Optical Fiber Access Network in Kuwait</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ali%20A.%20Hammadi">Ali A.

The work covers the framework of the conceptual design of the deployed Passive Optical Networks (PONs), access network, optical fiber cable network distribution, technologies, and standards. The work also describes methodologies applied by system engineers for design of Optical Network Terminals (ONTs) and Optical Line Terminals (OLTs) transceivers with respect to the distance, operating wavelengths, splitting ratios. The results have demonstrated and justified the limitation of transmission distance of a PON link in Fiber to The Premises (FTTP) to not exceed 20 km. Optical Time Domain Reflector (OTDR) test has been carried for this project to confirm compliance with International Telecommunication Union (ITU) specifications regarding the total length of the deployed optical cable, total loss in dB, and loss per km in dB/km with respect to the operating wavelengths. OTDR test results with traces for segments of implemented fiber network will be provided and discussed.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Passive%20optical%20networks" title="Passive optical networks">Passive optical networks</a>, <a href="https://publications.waset.org/search?q=fiber%20to%20the%20premises" title=" fiber to the premises"> fiber to the premises</a>, <a href="https://publications.waset.org/search?q=access%20network" title=" access network"> access network</a>, <a href="https://publications.waset.org/search?q=OTDR." title=" OTDR."> OTDR.</a> </p> <a href="https://publications.waset.org/10008581/a-framework-for-the-design-of-green-giga-passive-optical-fiber-access-network-in-kuwait" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10008581/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10008581/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10008581/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10008581/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10008581/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10008581/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10008581/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10008581/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10008581/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10008581/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10008581.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1067</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">604</span> Coherent PON for NG-PON2: 40Gbps Downstream Transmission with 40dB Power Margin using Commercial DFB Lasers and no Optical Amplification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Roberto%20Gaudino">Roberto Gaudino</a>, <a href="https://publications.waset.org/search?q=Antonino%20Nespola"> Antonino Nespola</a>, <a href="https://publications.waset.org/search?q=Dario%20Zeolla"> Dario Zeolla</a>, <a href="https://publications.waset.org/search?q=Stefano%20Straullu"> Stefano Straullu</a>, <a href="https://publications.waset.org/search?q=Vittorio%20Curri"> Vittorio Curri</a>, <a href="https://publications.waset.org/search?q=Gabriella%20Bosco"> Gabriella Bosco</a>, <a href="https://publications.waset.org/search?q=Roberto%20Cigliutti"> Roberto Cigliutti</a>, <a href="https://publications.waset.org/search?q=Stefano%20Capriata"> Stefano Capriata</a>, <a href="https://publications.waset.org/search?q=Paolo%20Solina."> Paolo Solina.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We demonstrate a 40Gbps downstream PON transmission based on PM-QPSK modulation using commercial DFB lasers without optical amplifier in the ODN, obtaining 40dB power budget.
