All-optical programmable Binary-to-Gray or Gray-to-Binary code converter using TOAD based reversible new multiplexer

Recently, reversible logic gate provides an alternative to overcome many problems in computing technologies as their zero-power dissipation under ideal condition and it is emerged as a promising computing paradigm with applications in low-power CMOS, quantum computing, optical computing and nanotechnology. Optical logic gates become potential component to work at macroscopic (light pulses carry information), or quantum (single photon carries information) levels with high efficiency. This paper proposes a low-power design of all-optical programmable Binary-to-Gray or Gray-to-Binary code converter using reversible new multiplexer in all-optical domain. By Matlab-7.0 the simulation results verify the functionality of both the new multiplexer and programmable code converter as well as reversibility.
