Implementation of XOR/XNOR and AND logic gates by using Mach–Zehnder interferometers

In this paper, the working principle of Mach–Zehnder interferometer is described. The paper focuses on the description of optical switching phenomena and its efficient application to perform digital logic operations such as AND, XOR and XNOR logic gates. It includes the important result of digital logic operation using the MATLAB and each result is verified through the OptiBPM software.
