Abstract
In this paper, the silicon micro-ring resonator (MRR) as nonlinear all-optical switch is described through two-photon absorption (TPA) effect. The all-optical scheme of reversible Peres-gate, Toffoli-gate, Fredkin-gate and TR gate using MRR are presented in this paper. Simulation results confirming described method are also presented in this paper. We identified a combination of feasible MRR radius and coupling coefficient through numerical simulation which allows analyzing the system performance of the scheme, as extinction-ratio (ER) and contrast-ratio (CR), confirms the feasibility of design. The proposed circuit may perform different arithmetic and logic operations in the reversible logic-based information-processing..
