Ultrafast all-optical switching in a silicon-based plasmonic nanoring resonator.

A silicon-based plasmonic nanoring resonator is proposed for ultrafast, all-optical switching applications. Full-wave numerical simulations demonstrate that the photogeneration of free carriers enables ultrafast switching of the device by shifting the transmission minimum of the resonator with a switching time of 3 ps. The compact 1.00 μm² device footprint demonstrates the potential for high integration density plasmonic circuitry based on this device geometry.
