研制了一种基于硅线波导嵌入液晶外包层的马赫-曾德尔光开关。开关操作在1550 nm的波长与1.86 V.mm的电压长度的产品，获得了一个300 μ m长的环回移相器的设备。在各种配向膜条件下定性地评估切换速度，并且当配向层相对于波导适当地定位时，分别实现7.9和8.4 ms的关断和接通时间。(C)2016日本应用物理学会
A Mach-Zehnder optical switch based on a Si wire waveguide embedded in a liquid crystal overcladding is developed. Switching operation at a wavelength of 1550 nm with a voltage-length product of 1.86 V.mm is obtained for a device with a 300-mu m-long loop-back phase shifter. The switching speed is qualitatively evaluated under various alignment film conditions, and switch-off and switch-on times of 7.9 and 8.4 ms, respectively, are achieved when the alignment layer is appropriately positioned relative to the waveguides.
