摘要

We observe couplings between orthogonally polarized modes in a birefringent whispering-gallery-mode resonator. The modes show strong interactions leading to polarization conversion and avoid mode crossings. We show that a phenomenological model, based on the coupled-mode theory, is in good agreement with the experiments. The device provides an excellent laboratory to perform controllable and tunable mode interactions.
