摘　　要：近年来,高品质因子的回音壁模式(WGM)光学微腔发展迅速,成为光学和物理领域的热点研究。光学微腔是一种微型光学元件,由于其微小的尺寸和高品质因子,可以加强光与物质的相互作用并使光在其中长时间存留。WGM光学微腔是光学微腔的典型代表之一,具有体积小、灵敏度高和寿命长等优点,目前,基于WGM光学微腔的应用主要集中在各类传感、激光器和滤波器等领域。然而,当前对WGM光学微腔的研究还未实现大规模生产,仅处于实验室研究阶段,工业化生产还存在成本高、制作工艺困难等缺点。文章重点介绍了WGM光学微腔的研究进展,阐述了回音壁材料对Q值的影响,近几年WGM光学微腔在传感、激光器和滤波器领域的应用,并提出了在可能实现全光网络的未来WGM光学微腔存在的挑战及进一步研究方向。对于后续研究,文章认为首先需降低成本、缩短时间,提高制备工艺的精度和效率;其次,需要解决微腔与光学器件耦合的问题,提高耦合效率并提高抗干扰能力;最后,需要解决腔体对环境的敏感性问题,以确保微腔在制备滤波器等器件时具有良好的稳定性。In recent years,high quality factor echo wall mode optical microcavities have developed rapidly and become a hot re search topic in the fields of optics and physics.Optical microcavity is a kind of micro optical element.Due to its small size and high⁃quality factor,it can enhance the interaction between light and matter,enabling long⁃time light stays.Echo wall mode resonators are one of the typical representatives of optical microcavities,with advantages of small size,high sensitivity,and long life.Cur rently,applications based on echo wall mode resonators are mainly concentrated in various fields such as sensors,lasers,filters,and so on.However,current research on echo wall mode resonators has not yet achieved large⁃scale production,and is only in the laboratory research stage.Industrial production still has shortcomings such as high cost and manufacturing process difficulties.This article focuses on the research progress of echo wall mode resonators,expounds the impact of echo wall materials on Q val ues,and discusses the applications of echo wall mode resonators in the fields of sensors,lasers,and filters in recent years.It also proposes the challenges and further research directions of echo wall mode resonators in the future,which may realize all⁃optical networks.For further research directions,we believe that it is necessary to reduce costs,shorten time,and improve the accuracy and efficiency of the preparation process.It is also necessary to solve the coupling problem between the microcavity and the optical device,improving the coupling efficiency and the anti⁃interference ability.It should also address the sensitivity of the cavity to the environment to ensure that the microcavity has good stability when preparing devices such as filters.
