Abstract :
Whispering-Gallery-Mode (WGM) resonators can significantly enhance light-matter interaction. We discuss self-pulsing behaviors in WGM microlasers due to nonlinear optical losses introduced by excited state absorption. Ultra-sensitive self-referencing detection of nanoparticles using WGM microlasers is demonstrated.
