We propose using two input beams to a bistable Kerr resonator for overcoming the thermal limitation to the switching speed between stable states. We theoretically demonstrate flip-flop operation by phase modulations of the inputs.
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.
We show through numerical simulations that optical pulses in silicon waveguides can undergo significant self-induced changes in their polarization state. These changes are mediated mostly by free-carrier dispersion and depend on waveguide dimensions.
