Paper Abstract

Whispering gallery mode (WGM) resonators are attracting increasing interest as possible frequency reference cavities. Unlike commonly used Fabry-Perot cavities, however, WGM resonators are dielectric resonators lled with a bulk medium whose properties have a signicant impact on the stability of its resonance frequencies. Thermal and other refraction index uctuations of the medium induce additional frequency instability that has to be reduced to a minimum. On the other hand, a small monolithic resonator provides opportunity for integration and immunity against vibration and acceleration disturbances. This feature is essential when the cavity operates in a non-laboratory environment. In this paper, we report a case study of vibration sensitivity reduction for a crystalline resonator and discuss a pathway towards the inhibition of vibration- and acceleration- induced frequency uctuations.
