Comparison of WGM in a face-shaped deformed OBH cavity and homogeneous cavity. Simulated WGM field of (a) deformed OBH cavity, and (b) deformed homogeneous cavity. White solid (dashed) curve is the deformed (circular) cavity boundary. c Comparison of Q-factor for a deformed OBH cavity (black curve) and homogeneous cavity (red curve) with various deformations. The resonant mode number is m = 5. d Comparison of Q-factor of deformed OBH (black curve) and homogeneous cavity (red curve) with different mode numbers
