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.
