Design of optical reversible logic gates using electro-optic effect of lithium niobate based Mach–Zehnder interferometers

Abstract

In recent years reversible logic has come as a promising solution in the optical computing domain. In reversible gates, there is one-to-one mapping between input and output, causing no loss of information. Reversible gates are useful for application in low power complementary metal-oxide semiconductors, with less dissipation, and in quantum computing. These benefits can be utilized by implementing reversible gate structures in the optical domain. In this paper, basic reversible Feynman and Fredkin logic gates using a lithium niobate based Mach–Zehnder interferometer are proposed. The different applications utilizing the proposed structures are also explained in this study.
