Abstract
We review recent progress in the application of whispering-gallery mode microresonators, such as
microspheres, microdisks, and microtoroids, in cavity Quantum Electrodynamics (QED). Particular
emphasis is made on the studies on the interaction of laser-cooled single atoms with evanescent fi eld of
monolithic microtoroidal resonators effi ciently coupled to tapered optical fi bers.
