Abstract
We report on the switching of an all-optical flip-flop consisting of a semiconductor optical
amplifier (SOA) and a distributed feedback laser diode (DFB),
bidirectionally coupled to each other. Both simulation and
experimental results are presented. Switching times as low as 50ps,
minimal required switch pulse energies below 1pJ and a repetition
rate of 1.25GHz have been measured. Contrast ratios over 25dB have
been obtained. The dependence on the pulse length and CW input power
of the minimal required switch energy is investigated. Related Research Topics
