摘要
基于液晶技术的太赫兹器件的研究开发已经成为该领域研究的重要方向之一。介绍了太赫兹器件的应用背景和太赫兹液晶器件的基本知识,并重点介绍了液晶在太赫兹频域的光电性质和材料特性,指出了若干有潜在可行性的液晶材料。在此基础之上对太赫兹液晶移相器、太赫兹可调液晶滤波器、太赫兹可调偏振器等液晶器件的设计原理和目前的研究结果进行了分析。最后,对太赫兹液晶器件的产品应用开发进行了总结分析,提出了此类元器件的研究开发方向。
Research and development of Terahertz （THz） devices based on liquid crystal technology have been one of the important research directions in the area of THz technology. The application background and ba- sic knowledge of THz liquid crystal device are introduced. The electro-optical and material properties of liquid crystal in the area of THz are discussed in detail. Some potential liquid crystal materials are introduced. Based on this, the design principle and presented research results of THz liquid crystal phase shifter, THz tunable liquid crystal filter and THz tunable polarizer are analyzed. The application developments of THz liquid crystal devices are summarized and analyzed finally. And research and development directions of the devices are proposed.
