Performance analysis of optical logic XOR gate using dual-control Tera Hertz Optical Asymmetric Demultiplexer (DCTOAD)

Abstract

In this paper we have proposed performance of optical logic XOR gate using dual control Tera Hertz Optical Asymmetric Demultiplexer (DCTOAD). For the first time DCTOAD based XOR gate with soliton pulse is proposed and analyzed in terms of eye diagram and quality factor. Extinction Ratio (ER), Contrast Ratio(CR) and relative eye opening are also calculated. High Q factor implies bit error free operation.
