Calculation of the Resonant Frequencies for a Whispering Gallery Mode Optical Resonator

A method of calculation of resonant frequencies and thus free spectral range of high-Q dielectric disk resonators with whispering gallery modes is proposed. The method is based on application to the dispersion equation derived for a die-lectric cylinder with unlimited length, dimensional quantization, due to the requirement of phase balance for the stand-ing waves in the resonator. The simplified expressions suitable for calculation of optical microcavities used in the devices of radio photons are obtained.
