Realization of Half Adder using 1x4 Demultiplexer based on Non-linear switching of GaAs-AlGaAs MRR

The proposed paper portrays the feasible enactment of all optical based demultiplexer logical functionality using the non-linearity switching of micro ring resonator and its respective application based other circuit designing. The conferred theoretical method exploits the single ring MRR structure which is GaAs-AlGaAs based. The 1-to-4-line demultiplexer circuit designed using just three MRR structure cascaded together to acquire the desired outcome. This gets possible by the usages of high-speed optical switching property of MRR. This leads to advance-grade data processing, higher bandwidth operation, size compactness. The detailed mathematical modeling of demultiplexer has been discussed thoroughly. And the resultant graphical output is accomplished using the MATLAB simulation program. The procured output is then verified using the conventional truth-table.
