All-optical switching of silicon disk resonator based on photothermal effect in metal–insulator–metal absorber
2014
Optics Letters
Efficient narrowband light absorption by a metal-insulator-metal (MIM) structure can lead to high-speed light-toheat conversion at a micro-or nanoscale. Such a MIM structure can serve as a heater for achieving all-optical light control based on the thermo-optical (TO) effect. Here we experimentally fabricated and characterized a novel alloptical switch based on a silicon microdisk integrated with a MIM light absorber. Direct integration of the absorber on top of the microdisk reduces the
