Apparatus and method for the implementation of a fully optical or - gate, the one individual soa (half conductor light amplifier) uses

摘要

There are a device and a method for implementing a fully optical logic or - gate discloses. The device comprises an optical pulse generator, a phase-coupled fiber laser (mlfl), a first optical splitter, first optical retardation stretching means, optical control means, a first optical coupler, a second optical splitter, second optical retardation stretching means, a third optical splitter, a with erbium doped fiber amplifier (edfa), conductor of a semiconductor light amplifier (soa), a second optical coupler and an optical analyzer. The first optical splitter divides the light, which is emitted by the mlfl on. The first and second optical delay stretching means produce a time delay. The optical control means control the intensity and polarization of the light. The first optical coupler generates the first input signal pattern signal as a measuring probes. The second optical splitter divides the light from the first optical coupler is emitted, on. The third optical splitter divides the second input signal pattern on. The erbium-doped fiber laser (edfa) amplifies the selected part of the second input signal pattern as a pumping signal. The soa couples the pump signal in the measuring probes signal with opposite directions in order to the fully optical logic or - operation to carry out. The second optical coupler couples a signal, which is emitted by the soa, in the ..
