All Optical Logic Full Adder Based On XPM Effect In SOA-MZI

Abstract

With the development of all optical networks, Requires that all optical system including logic gate is consistent with the new format. We proposed and demonstrated a novel structure of ultrafast all optical full adder based on the Cross-phase modulation (XPM) that is principle nonlinear effect in a semiconductor optical amplifier (SOA) assisted mach zehnder interferometer (MZI). In this architecture quantum logic gates including: Feynman, Toffoli and Peres gates are used to implement all optical full adder. By using the presented structure, we obtain low power penalty for designed full adder and error-free performance at 10Gb/s and the receiver sensitivity for a bit-error rate of 10-9 is below -10dbm. In additional, the results show this structure will enhance the future optical signal processing application for ultrafast operation.
