Abstract :
We have demonstrated for the first time an all-optical flip-flop based on optical bistability of an integrated SOA/DFB-SOA by applying an input signal with the period of 25.2 ns. An all-optical flip-flop based on optical bistability is expected to process the signal at an ultra-high speed in a light-wave communication. All-optical flip-flop has various applications such as all optical memory, demultiplexing, packet-header buffering, and retiming. Moreover, an integrated SOA/DFBSOA can perform all-optical logic operation and wavelength conversion by cross gain modulation.
