Abstract :
We demonstrate all-optical bistable memory operation with 1.3 Q-InGaAsP photonic crystal nanocavities based on refractive index modulation caused by carrier-induced nonlinearity. The minimum bias power for bistability is extremely low at a few tens of muW and the operating energy required for switching is only 30 fJ.
