摘要：
Whispering gallery mode (WGM) microcavity laser is a micro/nano laser device which can confine light in micro/nano resonant cavity and maintain stable traveling wave transmission mode. With its high quality factor and small mode volume, WGM microcavity laser has the advantages of low threshold and narrow linewidth. It has become a hot research field at home and abroad. WGM microcavity has a very high optical energy density, and the interaction between light and material is significantly enhanced. In recent years, researchers have combined different gain materials with different microcavity structures, which has greatly promoted the development of WGM microcavity lasers. Based on the overview of the characteristic parameters and coupling mode of WGM microcavity lasers, this paper introduces the research results of several typical WGM microcavity lasers, including droplet microcavity, glass microcavity and semiconductor microcavity, and compares their performance parameters. The applications of the devices in ultra sensitive sensing, microwave photonics and on-chip integration are described, and the development trend of WGM microcavity lasers is prospected. © 2022 Chines Academy of Sciences.
