Optical whispering‐gallery mode (WGM) microcavities featuring ultrahigh Q factors and
small mode volumes enhance significantly the interaction between light and matter …

A fiber-based whispering-gallery-mode (WGM) microprobe, combining both the high optical
field enhancement of the WGMs and the compact structure of the optical fiber, is highly …

Photonic crystal split-beam nanocavities allow for ultra-sensitive optomechanical
transductions but are degraded due to their relatively low optical quality factors. We have …

Directional light emission from high-Q resonant modes without significant Q-spoiling has
been a long standing issue in deformed dielectric cavities. In limaçon-shaped gradient index …

Recently, gradient index cavities, or so-called transformation cavities, designed by
conformal transformation optics, have been studied to support resonant modes with both …

Ultralong distance coupling between two deformed circular microcavities (DCMs) is studied.
