Abstract :
We investigate the optical modes of hollow ring resonator with omnidirectional reflector cladding by numerical method. We demonstrate that each TM0ml mode (or TE0ml mode) can split into two modes whose wavelengths are very close. The doublet effect is caused by the symmetry breaking at circular cross section when a straight waveguide is curled into a ring shape. The ring-shaped hollow Bragg cavity provides a platform to research the interaction of Rydberg atoms and light mode.
