초록

We have demonstrated all-opticalflip-flop based on optical bistability in a SOA/DFB-SOA with broadband gain. Input signal with the wavelength of 1340.23 nm or 1680.93 nm and the current of about 98% of the lasing threshold is injected into theDFB-SOA. Current injected into SOA is 80 mA All-optical flip-flop has various applications such as all-optical memory, demultiplexing, packet-header buffering, and retiming.
