In this chapter light coupling mechanisms to MDR’s is examined. The novel mechanism of excitation of the microsphere with an optical fiber coupler (OFC) provides spatially and spectrally selective, as well as enhanced light coupling to the MDR’s, when compared with the conventional plane wave excitation. The plane wave excitation is described by LorenzMie Theory. However, Generalized Lorenz-Mie Theory and the Localization Principle are used for the OFC excitation.EnglishImpact parameterGaussian beamTransverse electricStimulate brillouin scatteringAngular momentum quantum numberBook Chapter10.1007/978-94-015-8796-9_129789401587969
