Abstract
Light can be confined efficiently in the high-Q, small-volume whisperi ng-gallery-modes observed in silica microspheres. By coupling these mi crospheres to eroded optical fibers and fiber tips, direct mapping of the whispering-gallery modes has been achieved and the mode numbers ha ve been assessed. The properties of these modes have allowed us to obt ain laser action with very low thresholds in Nd-doped silica microsphe res. Further projects in the field of non-linear optics and cavity qua ntum electrodynamics are described.
