Design and Implementation of Full-Subtractor Using 4 to 1 Line Multiplexer Based on Micro Ring Resonator Nonlinear Switching

This paper manifest a prominent method for designing full-subtractor using 4 to 1 line multiplexer based on all optical switching action of Micro Ring Resonator. Proposed theoretical model utilizes the feasible properties of MRR, which proves to be more efficient and effective to get the stable output. Here the switching activity of MRR in sync with the working of MUX in conjunction with the corresponding figure and graph are explained. Also the mathematical equation of the required MRR working operation has been discussed deeply. The MUX circuit design used here is formed by the network of MRRs cascaded together. To accomplish the output of full-subtracter, we considered ‘B’ as the data line and other two as the required select line. The validation of the logical output behavior of the implemented 4 to 1 line MUX was endorsed using simulation obtained from MATLAB.
