    "abstract": "A general model is presented for coupling of high-$Q$ whispering-gallery\nmodes in optical microsphere resonators with coupler devices possessing\ndiscrete and continuous spectrum of propagating modes. By contrast to\nconventional high-Q optical cavities, in microspheres independence of high\nintrinsic quality-factor and controllable parameters of coupling via evanescent\nfield offer variety of regimes earlier available in RF devices. The theory is\napplied to the earlier-reported data on different types of couplers to\nmicrosphere resonators and complemented by experimental demonstration of\nenhanced coupling efficiency (about 80%) and variable loading regimes with\nQ\u003e10^8 fused silica microspheres.",
