Design of Optically Controlled Reversible NOT Gate Using Micro Ring Resonators

Abstract

Micro Ring Resonator (MRR) is a successful micro-device with the help of which different types of optical logic gates, logic processors, arithmetic units, etc. can be designed and integrated easily into the modern high-speed communication network. In this article, at first, the author has explained the switching mechanism of MRR and then designed an optically controlled Feynman gate (i.e. reversible controlled-Not gate) using MRRs. The switching mechanism of MRR is reliable and the switching speed of MRR is very fast. The change the resonance condition of MRR can occur when the ring is exposed in the optical pump beam with high intensity. The logic processors using Reversible Logic gates are more acceptable due to their data recovery capability and low power consumption. The designed circuit of optically controlled NOT Gate is testified with the MATLAB simulation results. To fulfil the demand for an ultra-high-speed network, the development of high speed optical logic processors is the primary requisite and this scheme will be very helpful for developing such elements.
