Design and Implementation of Full Adder using 4 to 1 line Multiplexer Based on Nonlinear Switching Micro Ring Resonator Structure

This paper intended to assert the designing of the four to one line multiplexer logic using nonlinear switching techniques based on Micro Ring Resonator (MRR) structure for the proposed full-adder circuit. And to get the desire result of full adder, for which ‘A’ as a data line has been considered. By using the MRR based all-optical switching technique the 4 to 1 line multiplexer logic system configuration has been achieved by applying the realization of the 2-to-4-line decoder to make the system more compact and optimized. The 2:4 decoder circuits have been theoretically implemented by cascading two or more MRRs. The using of 4 to 1 multiplexer to implement the full adder circuit adds some additional advantages such as desired bandwidth can be obtained, advanced data processing. The MRR switching activity, which is the proposed circuit design has been explained in detail with mathematical derivations and results have been verified by performing the MATLAB simulation.
