摘要
In this paper the design and simulation of an all-optical three-input exclusive-OR (XOR) gate based on semiconductor optical amplifier-Mach-Zehnder interferometer (SOA-MZI) configuration is presented. This gate is constructed of three semiconductor optical amplifiers placed at the arms of the two coupled Mach-Zehnder interferometers. The outputs of these two MZIs are combined at the output port to form the final signal. The proposed scheme does not need a continuous wave (CW) laser for its operation and is designed so that the minimum number SOAs are employed. Theoretical analyses and simulations show that this structure acts as an all-optical three-input XOR logic gate which has many applications in optical data communications.
