Abstract

We fabricated crystalline whispering gallery mode microresonators with an ultrahigh Q close to 108 without polishing by employing a computer-controlled ultraprecision machining process. The dispersion of the fabricated device agrees well with the design, which indicates that the resonator cross-section is precisely controlled.
