摘要

我们提出并演示了一种基于液晶(LC)的太赫兹移相器，该移相器具有厚(总厚度为550 μm)的双层LC电池结构，其中包含一层薄的透明聚合物中间层。该移相器的性能得到了显著改善。相移由940增加到1110;与单层电池结构相比，阈值电压和驱动电压分别从2.2 VRMS降低到1 VRMS，从10 VRMS降低到8.4 VRMS。

Liquid Crystal Based Terahertz Phase Shifter with Bi-Layer Structure

We propose and demonstrate a liquid crystal (LC) based terahertz phase shifter with a thick (550 μm in total) bi-layer LC cell structure incorporating a thin transparent polymeric intermediate layer. The present phase shifter exhibited remarkable performance improvement. The phase shift increased from 94o to 111o; threshold and drive voltages decreased from 2.2 VRMS to 1 VRMS and from 10 VRMS to 8.4 VRMS, respectively, in comparison with those for single-layer cell structure.
