Abstract
The performance of XOR, NOR, and NAND functions implemented all-optically (AO) using two parallel semiconductor optical amplifier (SOA)-based Mach-Zehnder interferometers is simulated and investigated. The dependence of the quality factor on key input signals and SOAs parameters is investigated and assessed. The obtained results show that the target AO Boolean functions can simultaneously be realized with the employed scheme with both logical correctness and high quality at 80 Gb/s.Keywords
