We report on the dynamic all-optical flip-flop (AOFF)
operation of an optical feedback scheme consisting of a semiconductor
optical amplifier (SOA) and a distributed feedback laser
diode (DFB-LD), bidirectionally coupled to each other. The operation
of the AOFF relies on the interplay between the optical powers
in both the DFB-LD and the SOA. Switching times as low as 150 ps
for switch pulse energies of around 6 pJ and a repetition rate of
500 MHz have been measured. The contrast ratio was measured to
be above 12 dB.
