Design and Simulation of All-Optical AND Gate using XGM in Semiconductor Optical Amplifiers without Input Additional Beam

Design and simulation of an all-optical AND gate that utilize a XGM in semiconductor optical amplifiers is demonstrated at 10 Gbps using only input signals A and B. In the AND (AB) gate, Boolean AB is firstly obtained by using signal B as a pump beam and signal A as a probe beam in SOA-1. By passing signal A as a probe beam and ABmacr as a pump beam through SOA-2, Boolean AB is acquired
