Abstract

We report on the development of a packaged optical whispering-gallery-mode (WGM) resonator exhibiting low vibration sensitivity. The fractional frequency shift is measured to be on the order of 10 −10 / g along the vertical axis and 10 −11 / g along the horizontal axis. The resonator, operating in the optical domain with an intrinsic quality factor of Q ∼10 9 , is employed for laser frequency stabilization. The resulting laser exhibited a relative frequency stability 3×10 −12 level at 10 ms integration time. These results highlight the potential of optical WGM resonators as compact, mechanically robust frequency references for precision photonic systems.
