Embodying equipment and method for an all-optical OR logic gate by using single SOA

摘要

The present invention is an all-optical OR logic device implements the gain saturation characteristics of a single device using a semiconductor optical amplifier (SOA) and relates to a method, and more particularly to a technique for implementing a new all-optical device of the all-optical logic OR logic operation by using the optical signal transmitted at any point in the optical circuit, such as the optical pump signal and the survey signal to computing. ; According to the present invention, the optical pulse generator for generating optical pulses; Mode-locked fiber laser for generating the input signal patterns A and B from the optical pulse generator (MLFL); A first optical splitter for separating the light output of the 50: 50 mode-locked fiber laser; First gwangji delegation for obtaining a time delay the output light from the first optical splitter; Light control means for controlling the output intensity of the light from the first optical splitter and the polarization; A first optical coupler for generating the input signal A as the irradiation pattern signal by combining the output light from the first gwangji delegation and light control means; A second optical splitter for separating an output light from a 50: 50 by the first optical coupler; The second output light from the optical splitter is time delayed input signal that will result in the second pattern B gwangji delegation; The input signal pattern B is the third optical splitter for separating the 50:50; Erbium-doped fiber amplifier for amplifying the input signal and the third pattern B side of a pump signal from the optical splitter (EDFA); A semiconductor optical amplifier, the pump signal and the survey signal is incident in the opposite direction (SOA); A second optical coupler for coupling the semiconductor output signal and the input signal pattern from the optical amplifier (B); And presents the all-optical OR logic device implementing device comprising the optical signal analyzer for analyzing and detecting the output light from the second optical coupler.
