We fabricated crystalline whispering gallery mode microresonators with an ultrahigh $Q$ close to 10 8 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.© 2019 The Author(s)
