Abstract

Reversible logic is an emerging research area, which can achieve the one-to-one mapping function to reduce the power dissipation has made these circuits lossless circuits. In this letter, we propose an on-chip optical Toffoli gate for reversible logic operation using silicon micro-ring resonators (MRRs). The possibility of using Silicon-on-insulator (SOI) based MRR as thermo-optic switch is described through thermo-optic effect. Three electrical input signals (logic operands) are applied across the micro-heaters above MRRs to determine the switching states of MRRs, and the reversible logic operation results are directed to the output ports in the form of light, respectively. For proof of concept, the scattering matrix method is employed to establish numerical model of the device. Simulation results confirming described method are presented in this paper. The proposed design is optimized in terms of optical cost and the delay and garbage output.
