Abstract :
We show that switching between the two stable states of an optical flip-flop, made using a two-input Kerr resonator, can be realized through pure phase modulation. The proposed switching mechanism is compatible with cross-phase modulation induced by set and reset pulses for realization of an ultrafast, passive, all-optical memory element.
