摘　　要：液晶作为液态和固态之间的中间态,具有液体的流动性和晶体的各向异性,其指向矢灵活可调,从微波到紫外都有广泛应用。近年来液晶光子学在太赫兹波段展现出巨大应用前景,本文综述了基于液晶的太赫兹源、可调太赫兹器件和太赫兹探测器的研究进展,探讨了未来液晶太赫兹光子学的发展趋势,如新型铁电向列相、液晶拓扑在太赫兹领域的应用,多模式、多参量的太赫兹波按需产生、调制与探测等。Liquid Crystal(LC),as an intermediate state between liquid and solid,has the fluidity of liquid and the anisotropy of crystal,and its director is flexible and tunable.It has a wide range of applications from microwave to ultraviolet.In recent years,LC photonics has shown great application prospects in the terahertz band.This paper reviews the research progress of LC-based terahertz sources,tunable terahertz devices and terahertz detectors,and discusses the future development of LC terahertz photonics such as ferroelectric nematic phase,liquid crystal topology,as well as multi-mode and multi-parameter on demand terahertz wave generation,modulation and detection.
