Abstract

We study level crossing in the optical whispering-gallery (WG) modes by using toroidal microcavities. Experimentally, we image the stationary envelope patterns of the composite optical modes that arise when WG modes of different wavelength coincide in frequency. Numerically, we calculate crossings of levels that correspond with the observed degenerate modes. In addition, we discuss the effects of symmetry and separability of the wave equation on the fine character of the crossing.
