Implementation of Optical XOR Gate and Gray to Binary Code Converter Using Mach-Zehnder Interferometer
Abstract: AbstractWith the progress in optical communication system, optical networks are demanding of all optical devices to improve the speed, power and to reduce the attenuation during transmission of signals. In this paper, execution of gray to binary code converter with the aid of semiconductor optical amplifier (SOA) based Mach-Zehnder interferometer (MZI) is proposed, with the help of all-optical XOR logic gate, which is also demonstrated by using SOA-MZI, where CW …
