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, τ=2.4 μs thermal time constant and a low electrical power consumption of P(π)=12.7 mW/π-phase shift were demonstrated representing a P(π)τ product of only 30.5 mW·μs in a compact device with a phase shifter of only ~10 μm long.
在这封信件中，我们提出并展示了一种使用绝热弯曲和直接集成硅加热器的高速、低功耗热光开关，以最小化热容量，从而最大限度地提高热光开关的性能。我们展示了一个快速的热时间常数τ=2.4 μs 和低的电功率消耗 P(π)=12.7 mW/π-相移，这在一个仅有~10 μm 长的相移器的紧凑设备中代表了仅为 30.5 mW·μs 的 P(π)τ 乘积。
