Reversible logic is emerging as a hot research topic, where there is a unique mapping between the input and the output vectors, finding its applications in various fields, such as low-power design, optical information processing, and quantum computation. Research is gaining importance towards optical implementation of reversible logic gates using Mach-Zehnder Interferometer (MZI) for its fast switching capability, low power, high degree of parallelism, etc. In this paper, we have proposed and evaluated the performance of an all optical design of reversible Thapliyal Srinivasan Gate (TSG) and Haghparast Navi Gate (HNG) gates using MZI which shows better performance in terms of Optical cost and delay than the existing counterpart. To the best of our knowledge MZI based optical design is not available for TSG and HNG gates.
