Abstract

Numerically, we have analyzed the basic characteristics of all-optical demultiplexing based on four-wave mixing in semiconductor optical amplifiers by solving a modified nonlinear Schrodinger equation using the finite-difference beam propagation method. For high on-off ratio, the optimum input pump pulsewidth is 1~3 ps for 1 ps, 250 Gbit/s probe pulse. From the simulation results, it is clear that for the faster demultiplexing operation, semiconductor optical amplifiers with wider gain bandwidth are required. We have simulated pattern effects in the FWM signal. We have also obtained demultiplexing from the time-multiplexed signals by repetitive pump pulses
