The strength of optomechanical interactions in a cavity optomechanical system can be quantified by a vacuum coupling rate g(0) analogous to cavity quantum electrodynamics. This single figure of merit removes the ambiguity in the frequently quoted coupling ...
We report the study of the optical and mechanical properties of high-Q fused silica microtoroidal resonators at cryogenic temperatures (down to 1.6 K). A thermally induced optical multistability is observed and theoretically described, originating from the ...
