Non-linear switching of GaAs-AlGaAs MRR based Half subtractor using 2-to-4 line Decoder

the descriptive paper proposes the scheme for the conveying half subtractor, that has been implemented by using 2-to-4-line decoder. This paper also expresses switching phenomenon allied with all optical micro ring resonator and shed some light in the basic working mechanism of MRR with promising results obtained by using simulating software application MATLAB. Mathematical equation that has been used for the construction and output calculation of MRR structure. In theoretical tactic GaAs-AlGaAs material is considered for the construction of MRR, which provides additional advantages over Silicon Nitride and other similar material. The proposed circuit of the half-subtractor comprises of only five MRR out of which 3 MRR is used for decoder purpose and rest 2 MRR are used to get the final output. The usages of all-optical nonlinear property enable the high-speed switching action without compromising other factors. The acquired simulated output has been confirmed by considering truth table.
