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. It is shown that the bistability behavior depends on thecontrol of the input wavelength.KeywordsAll optical flip-flops, Kerr effect, microringresonator, optical bistability.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=All%20optical%20flip-flops" title="All optical flip-flops">All optical flip-flops</a>, <a href="https://publications.waset.org/search?q=Kerr%20effect" title=" Kerr effect"> Kerr effect</a>, <a href="https://publications.waset.org/search?q=microring%20resonator" title=" microring resonator"> microring resonator</a>, <a href="https://publications.waset.org/search?q=optical%20bistability." title=" optical bistability."> optical bistability.</a> </p> <a href="https://publications.waset.org/1869/exploiting-silicon-on-insulator-microring-resonator-bistability-behavior-for-all-optical-set-reset-flip-flop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/1869/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/1869/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/1869/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/1869/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/1869/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/1869/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/1869/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/1869/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/1869/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/1869/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/1869.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">2144</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">1</span> XPM Response of Multiple Quantum Well chirped DFB-SOA All Optical Flip-Flop Switching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Masoud%20Jabbari">Masoud Jabbari</a>, <a href="https://publications.waset.org/search?q=Mohammad%20Kazem%20Moravvej-Farshi"> Mohammad Kazem Moravvej-Farshi</a>, <a href="https://publications.waset.org/search?q=Rahim%20Ghayour"> Rahim Ghayour</a>, <a href="https://publications.waset.org/search?q=Abbas%20Zarifkar"> Abbas Zarifkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this paper, based on the coupled-mode and carrier rate equations, derivation of a dynamic model and numerically analysis of a MQW chirped DFB-SOA all-optical flip-flop is done precisely. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the DFB-SOA all optical flip flop. We have shown that strained MQW active region in under an optimized condition into a DFB-SOA with chirped grating can improve the switching ON speed limitation in such a of the device, significantly while the fall time is increased. The values of the rise times for such an all optical flip-flop, are obtained in an optimized condition, areas tr=255ps.</p> <p class="card-text"><strong>Keywords:</strong> <a
