All Optical Switching Logic Gates Based on Nonlinear Semiconductor Optical Amplifiers Effects

Abstract

This paper studies the problem of data access at the receiver withlarge bit error rate and low quality factor. Due to this issue theinformation got inaccurately at the receiver side, the data shouldhave high quality factor and low bit error rate to be simple ofidentification at the receiver when using the gates. The nonlinearproperties of the semiconductor optical amplifier (SOA) are utilizedto accomplish the Boolean variable based math work, in whichAND, NAND, and OR gates potentially used to endorse theBoolean function. Through blend this gates together any Booleanfunction can be accomplished and utilized to perform optical signalprocessing. The quality factor and BER are measured by utilizingthe eye diagram analyzer, the state of the output bit and alsoshaped by the oscilloscope visualizer in Optiwave simulationprogram. These models can be used for wavelength converter,header recognition, parity checking, binary addition, packet-headermodification, encoding and encryption with pattern matching, anddata encryption with high speed and high quality factor.
