Abstract :
An all-optical flip-flop memory with separate set and reset inputs is presented. The flip-flop is realised from two coupled polarisation switches. The concept is explained and experimental results are presented that demonstrate that a contrast ratio of 20 dB and a switching power of <-3 dBm can be obtained. The all-optical flip-flop can be utilised in all-optical packet switches
