Abstract

Semiconductor optical amplifier (SOA) module, RSOA, SOA with mirror has become an essential component to be at the head of negative feedback amplification effect, optimum gain, and cross-gain modulation with demand for longer transmission lengths. The SOA module is expected to have an advantage of exhibiting much faster negative feedback (NF) response because distance of optical signal passing through component to component is shorten than system connected with fibers. Scattered degree and baseline line difference of eye-pattern diagrams demonstrated that NF effect can be compensated compactness and stability from band pass filter in SOA module. Modulation degree (MD) of input and output signals confirmed that SOA module with NF effect can be stabilized gain and waveguide of output signal and reduced a wave distortion as well as consistent with results in eye-pattern waveform and bit error rate (BER). All-optical switching triode with SOA module was realized in about 60 % output modulation degree at control power range of 0.01 to 1 mW. We propose that our manufactured SOA module become strong component candidate to realize all optical switching triode with NF effect for high speed optical processing in next generation.
