All-optical reversible multiplexer

The advantages of reversible logic systems and circuits have drawn a significant interest in recent years as a promising computing paradigm having application in low power CMOS, quantum computing, nanotechnology, and optical computing. This paper proposes a novel reversible multiplexer circuit with the help of all-optical Toffoli and Feynman gate. Operational principle of reversible multiplexer is described and is supported with logical simulation.
