AbstractTwo types of semiconductor optical amplifier (SOA) – based optical gate are investigated, the Mach-Zender Interferometer (MZI),Ultra fast nonlinear interferometer (UNI). The gate are characterized by switch window calculation. The switching windows are evaluated using different criteria such as switching width and on-off contrast ratio to compare the performance of the gates.The results indicate clearly that, with a suitable parameters control, a switching window width of ≈ 2ps and on-off contrast ratio below -11 dB can be achieved. The performance of the gates are investigated for demultiplexing application using the integrated contrast ratio (ICR). Simulation results are presented for OTDM bit rates up to 560 Gb/s and base data rate of 10Gb/s and 40Gb/s. the effect of SOA injection current ,control pulse energy and SOA length also presented.
