摘要
Trapping light without absorbing it is of great importance for both science and technology.A conventional way for trapping light is to use some kind of reflecting surface or region,namely a mirror,to forbid light escaping.Following this key concept,various optical resonators had been demonstrated,such as whispering-gallery mode cavity,photonic crystal defect cavity,micro-ring resonator,etc.
