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, tau = 2.4 mu s thermal time constant and a low electrical power consumption of P-pi = 12.7 mW/pi-phase shift were demonstrated representing a P-pi tau product of only 30.5 mW.mu s in a compact device with a phase shifter of only similar to 10 mu m long.
