All-Optical, All-Fibered Ultrafast Switching in 2-D InP-Based Photonic Crystal Nanocavity

The ultrafast optical switching capabilities of an InP-based photonic crystal cavity with quantum dots (QDs) are studied. The signal is evanescently coupled into the cavity at 1.5 μm through a tapered fiber. Both surface and fiber-coupled pumping schemes are investigated and compared. It is shown that the carrier-induced nonlinear response allows the signal… CONTINUE READING
