论文摘要
我们提出并展示了具有高功率效率和快速响应时间的2乘2热开关的被动偏见2乘2。该设备受益于插槽波导模式的高度浓缩光场以及列液晶（NLC）覆层的强热效应。 NLC填充纳米槽区域，并通过内部的亚波长度对齐。测得的功耗和热时间常数分别为0.58 MW和11.8微秒，对应于6.8的平均值。拟议的硅有机混合设备为设计具有较低功耗和快速运行速度的热光执行器提供了新的解决方案。
We propose and demonstrate a passively biased 2 by 2 thermo-optic switch with high power efficiency and fast response time. The device benefits from the highly concentrated optical field of a slot waveguide mode and the strong thermo-optic effect of a nematic liquid crystal (NLC) cladding. The NLC fills the nano-slot region and is aligned by the subwavelength grating inside. The measured power consumption and thermal time constant are 0.58 mW and 11.8 microsecond, respectively, corresponding to a figure-of-merit of 6.8. The proposed silicon-organic hybrid device provides a new solution to design thermo-optic actuators having lower power consumption and fast operation speed.
