A New System for All-optical AND Logic gate on Semiconductor Optical Amplifier based Michelson

Abstract

In this paper, the semiconductor optical amplifier (SOA) is used with a Michelson interferometer (MI) forming a structure of SOA-MI logic devices with symmetrically identical Fiber Bragg Grating (FBG) at the output of each of its arms, to a numerical simulation of the all-optical AND logic gate of two binary input data signals with different bit numbers using crossgain modulation (XGM) technique at 10 Gb/s bit rate and filter bandwidth at 10, 20 and 40 GHz using OptiSystem 15.0 software from OptiWave Corporation, to demonstrate and extract simple design rules for high-speed optical processing and analysis of non-linear SOA-induced properties. In addition, this work includes the study of the effect of bandwidth and number of bits on received power, minimum bit error rate (BER) and maximum quality factor (Q-factor) and Optical Signal to Noise Ratio (OSNR). We run the SOA-MI-based AND logic gate with some parameters and the results can demonstrate a structure of highperformance optical logic devices with high speed.
