An Analytical Approach to Realize Hypersecant Optical Soliton Pulse Based HALF-ADDER

Abstract

In this paper, we present a new method to perform all optical HALF ADDER by using Hypersecant Optical Soliton Pulse (HOSP). To implement this logic operation, we use four HOSP, out of which two are used as a form of signal pulse and other two as triggering pulse. Soliton pulse interacts with each other with a definite phase relationship and then output changes in accordance with applied condition. In this way we get output logic as a HALF-ADDER circuit. The logic GATE concept by using soliton is a new idea on nonlinear Photonics. The method of soliton superposition is simulated by MATLAB simulator and the result confirms the logical truth table for HALF ADDER.
