Ultracompact, low-power and ultrafast optical switching based on silicon photonic crystals
We demonstrate a silicon optical switch that can reroute optical signals within a switching time of just 3 ps. The switch is based on photonic crystal waveguides in a directional coupler geometry. The dispersion of the device has been engineered to provide slow-light enhancement, which allows the switching length of the device to be just 5 p.m. The 3 ps switching time is demonstrated using freecarriers in the silicon generated by the absorption of a femtosecond laser pulse.
