On-Chip All-Optical Switching and Memory by Silicon Photonic Crystal Nanocavities
Figure 3
Temporal response of thermo-optic switching. (a) Switch-off. Temporal
response of the probe output. At nanoseconds, the pump signal was
switched off. The input instantaneous power for the pump is 64 μW. The pulse width and period are 400 nanoseconds
and 40 microseconds. The exponential fit gives a decay time of approximately
100 nanoseconds. (b) Switch-on operation for various input power. (c) Incident
energy required for the switch-on operation estimated from the product of the
incident energy and the time required for switch-on in (b).
