Design and Implementation of 2-Input OR Gate based on XGM properties of Semiconductor Optical Amplifier

Abstract

In this paper we have implemented an all-optical OR-gate using simultaneous Four-Wave Mixing (FWM) and Cross-Gain Modulation (XGM) in a semiconductor optical amplifier (SOA).Which incorporates two semiconductor optical amplifiers (SOAs).The proposed OR logic is numerically simulated by solving nonlinear coupled equations that explain cross gain modulation(XGM) effect in individual SOAs.
