All optical 2-bit Carry Look Ahead Adder using Mach-Zehnder Interferometer

Abstract

In future for high speed processing all-optical logic Carry Look Ahead (CLA) Adder is extremely important and it is proposed and described with the help of semiconductor optical amplifier (SOA) based Symmetric Mach Zehnder Interferometer (SMZI) switch. In this present communication, we have tried to design a all-optical circuit CLA adder circuit. Simulation of proposed design has also been reported.
