Design and Performance Investigations with Ultra High Speed Optical ALU

Abstract

Abstract All-optical arithmetic and logic unit is an integral part of contemporary optical data processing network. Accordingly, in this paper a method to develop all-optical arithmetic unit has been proposed. The proposed logic unit consists of semiconductor optical amplifier (SOA) whose fast non-linear characteristics have been utilized for the execution of numerous binary logic operations such as AND, OR, NAND, NOR, EXOR, buffer etc., as well as arithmetic operations, for instance half-addition and half-subtraction, etc. Numerical simulations for the various logic operations have been realized and output verified for the 100 Gbps data rate. Numerical executions have been also done for the crucial key parameters as the bias voltage, confinement factor, and laser power, yielded with good extinction ratio more than 10 dB. The proposed design consists of SOA with benefits of design as rapid switching speed, consumes low power and avoids optoelectronic translation. The design is having with good prospect for impending all optical complex computing networks.
