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.
