simulating human skin have been actively studied, their completeness is unclear because skin tissue has the intricate optical property and complicated structure disturbing the optical simulation. In this study, we designed multilayer OTP mimicking skin structure, and fabricated OTP models simulating skin-blood vessel and skin pigmentation in the skin, which are useful in Biomedical optics filed. The OTPs were characterized with the optical property and the cross-sectional structure, and analyzed by using various optical tools such as a laser speckle imaging system, OCT and a digital microscope to show the practicality. The measured optical property was within 5% error, and the thickness of each layer was uniform within 10% error in micrometer scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20vessel" title="blood vessel">blood vessel</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20tissue%20phantom" title=" optical tissue phantom"> optical tissue phantom</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20property" title=" optical property"> optical property</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20tissue" title=" skin tissue"> skin tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=pigmentation" title=" pigmentation"> pigmentation</a> </p> <a href="https://publications.waset.org/abstracts/68389/fabrication-of-optical-tissue-phantoms-simulating-human-skin-and-their-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68389.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">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3196</span> Impact of Gd³⁺ Substitution on Structural, Optical and Magnetic Properties of ZnFe₂O₄ Nanoparticles </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raghvendra%20Singh%20Yadav">Raghvendra Singh Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivo%20Ku%C5%99itka"> Ivo Kuřitka</a>, <a href="https://publications.waset.org/abstracts/search?q=Jarmila%20%20Vilcakova"> Jarmila Vilcakova</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Urbanek"> Pavel Urbanek</a>, <a href="https://publications.waset.org/abstracts/search?q=Michal%20Machovsky"> Michal Machovsky</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Skoda"> David Skoda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this report, the impact of Gd³⁺ substitution in ZnFe₂O₄ spinel ferrite nanoparticles on structural, optical and magnetic properties was investigated. ZnFe₂₋ₓGdₓO₄ (x=0.00, 0.05, 0.10, 0.15, 0.20) nanoparticles were synthesized by honey-mediated sol-gel combustion method. X-ray diffraction, Raman Spectroscopy and Fourier Transform Infrared Spectroscopy confirmed the formation of cubic spinel ferrite crystal structure. The morphology and elemental analysis were studied using field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray spectroscopy, respectively. UV-Visible reflectance spectroscopy revealed band gap variation with concentration of Gd³⁺ substitution in ZnFe₂O₄ nanoparticles. Magnetic property was studied using vibrating sample magnetometer at room temperature. The synthesized spinel ferrite nanoparticles showed ferromagnetic behaviour. The evaluated magnetic parameters such as saturation magnetization, coercivity and remanence showed variation with Gd³⁺ substitution in spinel ferrite nanoparticles.

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/abstracts/search?q=all-optical%20networks" title="all-optical networks">all-optical networks</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20crosstalk" title=" optical crosstalk"> optical crosstalk</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20cross-connect" title=" optical cross-connect"> optical cross-connect</a>, <a href="https://publications.waset.org/abstracts/search?q=crosstalk" title=" crosstalk"> crosstalk</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20crosstalk" title=" monitoring crosstalk"> monitoring crosstalk</a> </p> <a href="https://publications.waset.org/abstracts/40796/monitoring-and-prediction-of-intra-crosstalk-in-all-optical-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40796.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">462</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3193</span> Optical Multicast over OBS Networks: An Approach Based on Code-Words and Tunable Decoders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Sliti">Maha Sliti</a>, <a href="https://publications.waset.org/abstracts/search?q=Walid%20Abdallah"> Walid Abdallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Boudriga"> Noureddine Boudriga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the frame of this work, we present an optical multicasting approach based on optical code-words. Our approach associates, in the edge node, an optical code-word to a group multicast address. In the core node, a set of tunable decoders are used to send a traffic data to multiple destinations based on the received code-word. The use of code-words, which correspond to the combination of an input port and a set of output ports, allows the implementation of an optical switching matrix. At the reception of a burst, it will be delayed in an optical memory. And, the received optical code-word is split to a set of tunable optical decoders. When it matches a configured code-word, the delayed burst is switched to a set of output ports. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20multicast" title="optical multicast">optical multicast</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20burst%20switching%20networks" title=" optical burst switching networks"> optical burst switching networks</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20code-words" title=" optical code-words"> optical code-words</a>, <a href="https://publications.waset.org/abstracts/search?q=tunable%20decoder" title=" tunable decoder"> tunable decoder</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20optical%20memory" title=" virtual optical memory"> virtual optical memory</a> </p> <a href="https://publications.waset.org/abstracts/11614/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/abstracts/11614.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">607</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3192</span> Reform of the Law Relating to Personal Property Security</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji%20Lian%20Yap">Ji Lian Yap</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper will critically consider developments in 2014 in relation to the law relating to security over personal property in Hong Kong.

Maximum data transmission using optimization of the communication channel poses the biggest challenge. Although there has been a constant focus on this area from the past decade, there was no evidence of a significant result that has been accomplished. Hence, after reviewing some potential design of optical network from literatures, it was understood that optical signal to noise ratio was one of the elementary attributes that can define the performance of the optical network. In this paper, we propose a framework termed as ECON (Enhanced Constraint-based Optical Network) that primarily optimize the optical signal to noise ratio using ROADM. The simulation is performed in Matlab and optical signal to noise ratio is extracted considering the system matrix. The outcome of the proposed study shows that optimized OSNR as compared to the existing studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=component" title="component">component</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20network" title=" optical network"> optical network</a>, <a href="https://publications.waset.org/abstracts/search?q=reconfigurable%20optical%20add-drop%20multiplexer" title=" reconfigurable optical add-drop multiplexer"> reconfigurable optical add-drop multiplexer</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20signal-to-noise%20ratio" title=" optical signal-to-noise ratio"> optical signal-to-noise ratio</a> </p> <a href="https://publications.waset.org/abstracts/17847/enhanced-constraint-based-optical-network-econ-for-enhancing-osnr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17847.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">488</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3190</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/abstracts/search?q=Leila%20Graini">Leila Graini</a> </p> <p class="card-text"><strong>Abstract:</strong></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. Our approach of all-optical 2R regeneration is based on those of Mamyshev.

On the one hand, the internet and advancements in technology have allowed for the widespread distribution and use of digital content, making it easier for individuals and businesses to access and share information. On the other hand, the rise of digital piracy and illegal file-sharing has led to increased concerns about the protection of intellectual property rights. This paper aims to examine the relationship between traditional property rights and online intellectual property rights in the digital age by analyzing the current legal frameworks, key challenges and controversies that arise, and potential solutions for addressing these issues. The paper will look at how traditional property rights concepts such as ownership and possession are being applied in the online context and how they intersect with new and evolving forms of intellectual property such as digital downloads, streaming services, and online content creation. It will also discuss the tension between the need for strong intellectual property protection to encourage creativity and innovation and the public interest in promoting access to information and knowledge. Ultimately, the paper will explore how the legal system can adapt to better balance the interests of property owners, creators, and users in the digital age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intellectual%20property" title="intellectual property">intellectual property</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20property" title=" traditional property"> traditional property</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20age" title=" digital age"> digital age</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20content" title=" digital content"> digital content</a> </p> <a href="https://publications.waset.org/abstracts/161600/examining-the-relationship-between-traditional-property-rights-and-online-intellectual-property-rights-in-the-digital-age" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161600.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">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3186</span> Wavelength Conversion of Dispersion Managed Solitons at 100 Gbps through Semiconductor Optical Amplifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kadam%20Bhambri">Kadam Bhambri</a>, <a href="https://publications.waset.org/abstracts/search?q=Neena%20Gupta"> Neena Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All optical wavelength conversion is essential in present day optical networks for transparent interoperability, contention resolution, and wavelength routing.

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.

Sorrell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Yttrium stabilized tetragonal zirconium polycrystalline (Y-TZP) has been used as a dental biomaterial. The strength and toughness of zirconia can be accounted for by its toughening mechanisms, such as crack deflection, zone shielding, contact shielding, and crack bridging. Prevention of crack propagation is of critical importance in high-fatigue situations, such as those encountered in mastication and para-function. However, the poor translucency of Y-TZP means that it may not meet the aesthetic requirements due to its white/grey appearance in polycrystalline form. To improve optical property of the Zirconia, precise evaluation of its refractive index is of significance. Zirconia`s optical properties need to be studied more in depth. Number of studies assumed, scattered light is isotropically distributed over all angles from biological media when defining optical parameters. Nevertheless, optical behaviour of real biological material depends on angular scattering of light by anisotropy material. Therefore, the average cosine of the scattering angle (which represent recovery phase function in the scattering angular distribution) usually characterized by anisotropy material. It has been identified that yttrium anti-sites present in the space charge layer have no significant role in the absorption of light in the visible range. Addition of cation dopant to polycrystalline zirconia results in segregate to grain boundaries and grain growth. Intrinsic and extrinsic properties of ZrO2 and their effect on optical properties need to be investigated. Intrinsic properties such as chemical composition, defect structure (oxygen vacancy), phase configuration (porosity, second phase) and distribution of phase need to be studied to comprehend their effect on refraction index, absorption/reflection and scattering. Extrinsic properties such as surface structure, thickness, underlying tooth structure, cement layer (type, thickness), and light source (natural, curing, artificial) of ZrO2 need to be studied to understand their effect on colour and translucency of material. This research reviewed effect of stabilization of tetragonal zirconia on optical property of zirconia for dental application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20properties" title="optical properties">optical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconia%20dental%20biomaterial" title=" zirconia dental biomaterial"> zirconia dental biomaterial</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title=" chemical composition"> chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20composition" title=" phase composition"> phase composition</a> </p> <a href="https://publications.waset.org/abstracts/39305/characterization-and-modification-of-the-optical-properties-of-zirconia-ceramics-for-aesthetic-dental-restorations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39305.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">395</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3179</span> Study and Analysis of Optical Intersatellite Links</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boudene%20Maamar">Boudene Maamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Mai"> Xu Mai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Optical Intersatellite Links (OISLs) are wireless communications using optical signals to interconnect satellites.

X-ray powder diffraction, Raman spectroscopy, UV-visible transmittance, and capacitance meter measurements have been used to characterize the structure, the functional groups, the optical parameters, and the dielectric constants of the material. 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 class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dielectric%20constants" title="dielectric constants">dielectric constants</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20band%20gap%20%28eg%29" title=" optical band gap (eg)"> optical band gap (eg)</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20parameters" title=" optical parameters"> optical parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20spectroscopy" title=" Raman spectroscopy"> Raman spectroscopy</a>, <a href="https://publications.waset.org/abstracts/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/abstracts/65237/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/abstracts/65237.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">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3172</span> Patented Free-Space Optical System for Auto Aligned Optical Beam Allowing to Compensate Mechanical Misalignments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aurelien%20Boutin">Aurelien Boutin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In optical systems such as Variable Optical Delay Lines, where a collimated beam has to go back and forth, corner cubes are used in order to keep the reflected beam parallel to the incoming beam. However, the reflected beam can be laterally shifted, which will lead to losses. In this paper, we report on a patented optical design that allows keeping the reflected beam with the exact same position and direction whatever the displacement of the corner cube leading to zero losses. After explaining how the optical design works and theoretically allows to compensate for any defects in the translation of the corner cube, we will present the results of experimental comparisons between a standard layout (i.e., only corner cubes) and our optical layout. To compare both optical layouts, we used a fiber-to-fiber coupling setup. It consists of a couple of lights from one fiber to the other, thanks to two lenses. The ensemble [fiber+lense] is fixed and called a collimator so that the light is coupled from one collimator to another. Each collimator was precisely made in order to have a precise working distance. In the experiment, we measured and compared the Insertion Losses (IL) variations between both collimators with the distance between them (i.e., natural Gaussian beam coupling losses) and between both collimators in the different optical layouts tested, with the same optical length propagation. We will show that the IL variations of our setup are less than 0.05dB with respect to the IL variations of collimators alone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=free-space%20optics" title="free-space optics">free-space optics</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20optical%20delay%20lines" title=" variable optical delay lines"> variable optical delay lines</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20cavity" title=" optical cavity"> optical cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=auto-alignment" title=" auto-alignment"> auto-alignment</a> </p> <a href="https://publications.waset.org/abstracts/152717/patented-free-space-optical-system-for-auto-aligned-optical-beam-allowing-to-compensate-mechanical-misalignments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152717.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">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3171</span> Deflection Effect on Mirror for Space Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maamar%20Fatouma">Maamar Fatouma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mirror optical performance can experience varying levels of stress and tolerances, which can have a notable impact on optical parametric systems. to ensure proper optical figure and position of mirror mounting within design tolerances, it is crucial to have a robust support structure in place for optical systems. The optical figure tolerance determines the allowable deviation from the ideal form of the mirror and the position tolerance determines the location and orientations of the optical axis of the optical systems. A variety of factors influence the optical figure of the mirror. Included are self-weight (Deflection), excitation from temperature change, temperature gradients and dimensional instability. This study employs an analytical approach and finite element method to examine the effects of stress resulting from mirror mounting on the wavefront passing through the mirror. The combined effect of tolerance and deflection on mirror performance is represented by an error budget. Numerical mirror mounting is presented to illustrate the space application of performance techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=opto-mechanical" title="opto-mechanical">opto-mechanical</a>, <a href="https://publications.waset.org/abstracts/search?q=bonded%20optic" title=" bonded optic"> bonded optic</a>, <a href="https://publications.waset.org/abstracts/search?q=tolerance" title=" tolerance"> tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=self-weight%20distortion" title=" self-weight distortion"> self-weight distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=Rayleigh%20criteria" title=" Rayleigh criteria"> Rayleigh criteria</a> </p> <a href="https://publications.waset.org/abstracts/172854/deflection-effect-on-mirror-for-space-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172854.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">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3170</span> Technology Assessment: Exploring Possibilities to Encounter Problems Faced by Intellectual Property through Blockchain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ismail">M.

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 multi-casting 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 multi-casting 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 class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20gain%20modulation" title="cross gain modulation">cross gain modulation</a>, <a href="https://publications.waset.org/abstracts/search?q=multicasting" title=" multicasting"> multicasting</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20feedback%20optical%20amplifier" title=" negative feedback optical amplifier"> negative feedback optical amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor%20optical%20amplifier" title=" semiconductor optical amplifier"> semiconductor optical amplifier</a> </p> <a href="https://publications.waset.org/abstracts/18462/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/abstracts/18462.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">684</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3168</span> Many-Body Effect on Optical Gain of n+ Doping Tensile-Strained Ge/GeSiSn Quantum Wells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20J.%20Fan">W.
