“…Spherical [27,28], cylindrical [26,[29][30][31], and more complex resonator morphologies [32] were considered. While there is no fundamental difference between the optical and microwave structures, they are practically dissimilar because of (i) the nature of attenuation in the resonator host material, and (ii) the WGM excitation techniques.…”

Optical whispering gallery modes (WGMs) derive their name from a famous acoustic phenomenon of guiding a wave by a curved boundary observed nearly a century ago. This phenomenon has a rather general nature, equally applicable to sound and all other waves. It enables resonators of unique properties attractive both in science and engineering. Very high quality factors of optical WGM resonators persisting in a wide wavelength range spanning from radio frequencies to ultraviolet light, their small mode volume, and tunable in-and out-coupling make them exceptionally efficient for nonlinear optical applications. Nonlinear optics facilitates interaction of photons with each other and with other physical systems, and is of prime importance in quantum optics. In this paper we review numerous applications of WGM resonators in nonlinear and quantum optics. We outline the current areas of interest, summarize progress, highlight difficulties, and discuss possible future development trends in these areas.

We propose a new microwave resonator technique of permittivity measurement in a small volume of a high lossy liquid sample. The technique is based on the use of a metal semispherical resonator filled with dielectric. The resonator contains a small semispherical central cavity filled up with a monitored liquid. The characteristic equations for eigen frequencies of electromagnetic oscillations in this resonator has been obtained rigorously and analyzed owing to high simmetry of the resonator with the liquid. On this basis the operating mode of oscillations and optimal sizes of the measuring cavity and the resonator have been found. We discovered the effect of electromagnetic field extrusion out of the small central cavity filled up with the liquid that has big values (much more than one) of the real and imaginary parts of permittivity. The technique has been implemented experimentally in X band. The found theoretically effect of the field extrusion has been confirmed experimentally. The relations for the complex permittivity of liquid using the measured values of the resonator quality factor and resonant frequency has been found.
