Abstract

Due to the limitation of materials, PIC cannot achieve large magnitude phase modulation in a small size, and lacks the reconfigurable ability. Because of its birefringence characteristic, liquid crystal can be used in the liquid crystal on silicon (LCoS) device to achieve a large amount of phase modulation in a small size and has the capacity of reconstruction. Based on the experimental results of LCoS devices and basic liquid crystal waveguide devices, the liquid crystal waveguide device is prepared. While retaining the LCoS spatial optical phase modulation capability, the liquid crystal waveguide and phase modulation capability are realized. The beam splitter, optical switch, and Mach–Zehnder interferometer structure are constructed, which verifies the feasibility of the liquid crystal waveguide phase modulator.

基于硅液晶的可重构波导器件研究
由于材料的限制,PIC 无法在较小的尺寸内实现较大的相位调制,并且缺乏可重构能力。液晶因其双折射特性,可用于硅基液晶(LCoS)器件,以较小的体积实现较大的相位调制量,并具有重构能力。根据 LCoS 器件和基本液晶波导器件的实验结果,制备了液晶波导器件。在保留 LCoS 空间光相位调制功能的同时,实现了液晶波导和相位调制功能。构建了分光器、光开关和马赫-泽恩德干涉仪结构,验证了液晶波导相位调制器的可行性。
