The interest for transmission capacity in overall information systems keeps on expanding because of developing utilization of Internet and high-transfer speed applications, for example, video.All-optical signal processing is one promising system for giving the essential limit and offers payload transparency, power utilization which scales proficiently with expanding bit rates, lessened handling inertness, and ultrafast signal processing.These networks do not have any optical to electrical converters because signal is photonic throughout its path and thus energy is conserved which is otherwise wasted in conversion of photons to electrons and back.Thus to achieve this, various configurations of Mach-Zehnder Interferometers are used which make signal processing quite fast and also power consumption is reduced.For all-optical switching to become a reality, integration is necessary to significantly reduce the cost of manufacturing, installation, and operation.One promising integrated all-optical logic gate is the semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) which has advantages like faster switching time, ease of fabrication, lesser power and high speed.As transistor count is increasing day by day, power consumption is increased so it has put a limit on transistor count.Therefore reversible logic has come into picture which has remarkable property of dissipating lesser power.So digital circuits are designed with only consists of reversible logic gates and thus researchers are aiming at designing new gates to reduce the optical cost and delay of the circuits.In this paper a new gate has been proposed and multiplexer design is shown with improved optical cost and delay and also various standard Boolean functions are also implemented using this new gate.
