Abstract

The increasing demand of speed turns the optical network to ultra-fast optical processing techniques such as switching, signal generation, arithmetic operations and many more. Interferometric based Semiconductor optical amplifier (SOA)-based mach-zehnder interferometer (MZI) has been of great interest in the field of ultra-fast all-optical signal processing. In this paper, SOA-MZI configuration is used to implement all-optical integrated half adder/subtractor (A/S) and full A/S by using optical tree architecture (TA). Simulations to analyze the logic device operation are done at 40Gbps by using different input bit sequences..
