摘要

Optical microcavities have attracted strong research interests,for their unique property of confining photons for a long time in small volumes,which significantly enhances light-matter interaction [1].In recent decades,various fabrication techniques of microcavities with higher quality factors (Q) and smaller mode volumes (Vm) have been developed,pushing forward studies from fundamental physics to functional photonics devices.Microcavity optomechanics provides an ideal platform for exploring the quantum nature of macroscopic objects [2],quantum information processing and precision measurement [3].Microcavities with deformed boundaries can act as an open billiard system,allowing for the study of classical and quantum chaos and directional lasing [4].The enhanced light-matter interaction characterized by the figure of merit Q/Vm enables ultrahigh sensitive optical sensors with the detection limit down to single nanoscale particles [5].Researchers in China have participated extensively in this area and made tremendous achievements.
