Abstract

An approach for fully vectorial modeling of cylindrical resonators based on the aperiodic Fourier modal method is proposed. The approach allows efficient and accurate calculations of the resonant wavelength, the quality factor, and the field of the whispering-gallery modes of rotationally symmetric resonators. The validity and the efficiency of the method are confirmed by the converged numerical results with microdisk and microring resonators as examples in comparison with other approaches.
