抄録

We developed a method for fabricating crystalline whispering gallery mode cavities based on laser-heated pedestal growth. We fabricated sapphire cavities and obtained a Q factor of 1.6 × 104 with a cavity whose radius was about 120 μm. We showed numerically that the cross sectional shape of the cavity is sensitive to the cavity Q, and we controlled it by changing the growth condition in the molten zone, without significantly degrading the crystal structure.
