Abstract

A novel architecture for an all-optical flip-flop is validated experimentally. The architecture comprises a single semiconductor optical amplifier–based Mach–Zehnder interferometer with an external feedback loop. The experimental results show optical bistable operation for a latching device with an on–off contrast ratio of 11 dB that employs set and reset pulses of less than 250 pJ, although the energy of these pulses could be greatly reduced by optical integration of the whole device.
