## Abstract A novel all‐optical logic OR gate based on cross‐gain modulation (XGM) using a two‐cascaded semiconductor optical amplifiers (SOAs) in a counterpropagating topology is presented. The attractive issue of the proposed method is that the logic OR gate can be obtained at a probe wavelength

Performance analysis is carried out for an all-optical wavelength converter based on cross-phase modulation in two semiconductor optical ampliÿers (SOAs) arranged in a Mach-Zehnder interferometer conÿguration to evaluate the e ciency of conversion and the signal-to-crosstalk ratio (SCR) at the outpu
The feasibility of an all-optical logic AND gate is demonstrated by using a semiconductor optical amplifier (SOA) based on the Mach-Zehnder interferometer (MZI). The AND results are numerically analyzed by solving the rate equation of SOA. The operation of the AND logic gate is experimentally demons
