This is a review on theoretical and experimental studies on dielectric microcavities, which
play a significant role in fundamental and applied research. The basic concepts and theories …

We experimentally report an asymmetrical spherical microcavity with thermal-induced
deformation, in which five-bounce whispering-gallery modes possess not only ultrahigh …

A recent experiment by Kwak et al.[Sci. Rep. 5, 9010 (2015) 10.1038/srep09010]
demonstrated the relevance of resonance-assisted tunneling for optical microcavities where …

In mixed phase space structures, the stable islands and chaotic sea are separated by
dynamical barriers. Considering the small tunneling rate, intuitively, the properties of long …

We investigate the efficient free-space excitation of high-Q resonance modes in deformed
microcavities via dynamical tunneling-assisted coupling. A quantum scattering theory is …

A whispering-gallery microcavity is an open optical system which supports well confined
counterpropagating electromagnetic waves. Deforming the boundary of the cavity or …

We present a new design of dielectric microcavities supporting modes with large quality
factors and highly directional light emission. The key idea is to place a point scatterer inside …
