    Abstract :

    Optical computers are attractive for future broadband optical communication which needed flexible optical processing devices. Optical logic gates are key element of these devices. Now a days most long distances telephone and internet communication is carried on optical fibers and optical switching has several advantages like high speed, low heating and economically viable. Nonlinear materials have tendency to change the optical properties employing nonlinear Kerr effect. The SPM, XPM, FWM in optical fiber is discussed in context of nonlinearity. Semi-conductor Optical Amplifier in Mach Zehnder Interferometer Configuration (SOA-MZI) is reviewed for optical logic gates. The essential features of semiconductor optical amplifier in MZI and NMZI are reviewed here. An investigation of various parameters like insertion loss, extinction Ratio, crosstalk for NMZI is done. The I/O characteristics have been discussed for variation in nonlinear arm, nonlinear coefficients, wavelengths of input beam, offset. A thorough theoretical review of fundamentals of all-optical communication has been presented.
