Abstract
We report the experimental realization of magneto-optical coupling between whispering-gallery modes in a germanate (56GeO2-31PbO-9Na2O-4Ga2O3) microspherical cavity due to the Faraday effect. An encapsulated gold conductor heats the resonator and tunes the quasi-transverse electric (TE) and quasi-transverse magnetic (TM) polarized modes with an efficiency of ∼ 65 fm/V at a peak-to-peak bias voltage of 4 V. The signal parameters for a number of heating regimes are quantified to confirm sensitivity to the generated magnetic field. The quasi-TE and quasi-TM resonance frequencies stably converge near the device's heating rate limit (equivalently, bias voltage limit) in order to minimize inherent geometrical birefringence. This functionality optimizes Faraday rotation and thus enables the observation of subsequent magneto-optics.
