On-Chip All-Optical Switching and Memory by Silicon Photonic Crystal Nanocavities

Figure 9

All-optical retiming circuit based on two bistable cavities. (a) Design based on a hexagonal air-hole 2D photonic crystal with  nm and a. Two waveguides in the upper area (PA and PC) are W1 and the other two in the lower area (PB and PD) are W0.8. (b) Simulated operation.
