摘　　要：近年来,液晶在光学微腔中的应用研究正成为一个前沿研究热点。高品质因子光学微腔可实现光的高度操控和调制,而液晶材料提供了额外的可调谐性和光学各向异性,丰富了光场调控物理机理。本文总结了液晶在光学微腔中的研究进展,特别关注了通过电场调控液晶分子取向以改变微腔内光场分布的特性,这一物理机制在偏振态调制等多个领域展现出了巨大潜力。其次探讨了液晶微腔光子学的最新研究动态,包括非厄米光子学、拓扑光子学以及CsPbBr_(3)钙钛矿液晶微腔激子极化激元调控等前沿领域,并讨论了这些进展如何为光学通信和信息处理带来新的研究机遇。最后,本文对液晶微腔相互作用机制的深入研究进行展望,以期为未来光子学器件和系统的发展提供一定的指导。In recent years,the application of liquid crystals in optical microcavities has emerged as a cutting-edge research hotspot.High-quality-factor optical microcavities enable precise control and modulation of light,while liquid crystals offer additional tunability and optical anisotropy,enriching the physical mechanisms of light field control.This paper summarizes the research progress of liquid crystals in optical microcavities,with a particular focus on the characteristic of changing the light field distribution within the microcavity by electrically regulating the orientation of liquid crystal molecules.This physical mechanism has shown great potential in polarization state modulation and other fields.Additionally,the latest research trends in liquid crystal microcavity photonics are discussed,including non-Hermitian photonics,topological photonics,and the manipulation of exciton-polariton condensates in liquid crystal microcavities with the perovskite CsPbBr_(3) as optically active material,and discuss how these advances may open up new research opportunities for optical communication and information processing.Finally,the paper looks forward to in-depth studies on the interaction mechanisms of liquid crystal microcavity,aiming to provide guidance for the development of future photonic devices and systems.
