@article{(Open Science Index):https://publications.waset.org/pdf/4727, title = {A Novel Single-Wavelength All-Optical Flip-Flop Employing Single SOA-MZI}, author = {H. Kaatuzian and M. Sedghi and S. Khatami}, country = {}, institution = {}, abstract = {In this paper, by exploiting a single semiconductor optical amplifier-Mach Zehnder Interferometer (SOA-MZI), an integratable all-optical flip-flop (AOFF) is proposed. 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.}, journal = {International Journal of Physical and Mathematical Sciences}, volume = {6}, number = {5}, year = {2012}, pages = {508 - 512}, ee = {https://publications.waset.org/pdf/4727}, url = {https://publications.waset.org/vol/65}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 65, 2012}, }
