摘要

With the development of plasmonic optical waveguides, numerous nanostructures based on different materials can be fabricated in a controlled way. While doing reversible computing, reversible logic gates are the necessary requirement to reduce the loss of information with less power consumption. The proposed design of the Feynman logic gate is simulated by a cascading metal-insulator-metal optical waveguide based on Mach-Zehnder interferometers. The footprint of the proposed Feynman logic gate is 62 mu m x 9 mu m, the extinction ratio is 10.57 dB, and the insertion loss is -0.969 dB and -1.191 dB, which is much better compared to an electro-optic-based exiting Feynman logic gate. The results are obtained by simulating the proposed structure using the finite difference time domain method and verified by using mathematical computation in MATLAB.
