Abstract :
We have demonstrated a broad-band all-optical flip-flop for wavelength-division-multiplexing system based on optical bistability in a semiconductor optical amplifier (SOA)/distributed feedback (DFB)-SOA with wide gain bandwidth for both SOA and DFB-SOA regions. Input signal with two different wavelength selections of 1530.45 and 1578.12 nm and the repetition ration of about 6 ns is injected into the SOA/DFB-SOA.
