Paper Abstract

A general model is presented for coupling of high-Q whispering-gallery modes in optical microsphere resonators with coupler devices possessing discrete and continuous spectrum of propagating modes. By contrast to Fabry-Perot resonators, in microspheres independent high intrinsic quality-factor and controllable parameters of coupling via evanescent field offer variety of regimes earlier available in RF devices. Latest results on realization of material- limited Q approximately 1010 in microspheres in the visible and near-infrared band and preservation of very-high Q in surface-hydration-preventing environment are presented.
