摘要

液晶作为宽波段外场可调谐材料在太赫兹波段具有显著的应用优势，有望实现高效、动态的太赫兹波前调控。本文简要综述了近年来南京大学液晶与微纳光学研究组和其他科研团队在基于液晶的太赫兹波前调控器件领域展开的部分研究，包括基于纯液晶的太赫兹调波器件和基于液晶集成超构表面的太赫兹调波器件两类，系统阐述了这些器件的动态可调谐、多样化功能的特征以及潜在的应用前景，并对液晶技术与太赫兹技术相结合的发展趋势进行了展望。

Abstract

Liquid crystal

with a broadband external field induced tunability

has obvious application advantages in the terahertz band. It is expected to realize efficient and active terahertz wavefront modulation. This article briefly summarizes some of the recent researches carried out by the group of liquid crystal and micro/nano optics of Nanjing University and other research teams in the field of liquid crystal based terahertz wavefront modulators. There are mainly two types

including pure liquid crystal based modulators and liquid crystal integrated metadevices. The characteristics of the dynamic tunability

diversified functions and potential application prospects of these devices are systematically described. The development trend of the combination of liquid crystal and terahertz technology is also discussed.
