Abstract
In this Letter, we propose and demonstrate a high-speed and power-efficient thermo-optic switch using an adiabatic bend with a directly integrated silicon heater to minimize the heat capacity and therein maximize the performance of the thermo-optic switch. A rapid, thermal time constant and a low electrical power consumption of -phase shift were demonstrated representing a product of only in a compact device with a phase shifter of only long.
