摘要
Disclosed herein is an apparatus and method for implementing an all-optical OR logic gate. The apparatus includes an optical pulse generator, a Mode-Locked Fiber Laser (MLFL), a first optical splitter, a first optical delay line means, an optical control means, a first optical coupler, a second optical splitter, a second optical delay line means, a third optical splitter, an Erbium Doped Fiber Amplifier (EDFA), a Semiconductor Optical Amplifier (SOA), a second optical coupler, and an optical analyzer. The first optical splitter divides light output from the MLFL. The first and second optical delay line means acquire time delay. The optical control means controls intensity and polarization of the light. The first optical coupler generates the first input signal pattern as a probe signal. The second optical splitter divides light output from the first optical coupler. The third optical splitter divides the second input signal pattern. The EDFA amplifies the divided part of the second input signal pattern as a pump signal. The SOA couples the pump signal with the probe signal in opposite directions to perform the all-optical OR logic operation. The second optical coupler couples a signal output from the SOA with the second input signal pattern.
