Abstract

We investigated the whispering gallery modes (WGMs) of cavities with a hexagonal cross section. We found two different modes, namely, perturbed and quasi-WGMs, of which the former exhibits a Q of greater than 107 when the corner radii are large and 1.8×104 when the corners are sharp. We studied the dependence of Q on the curvature radius of the polygonal cavities and found that the coupling between the two modes determines the Q of the cavity.
