We report guided-light opto-mechanical sensing of the mechanical vibrations of a toroidal-lipped SiO 2 GOBLiT. An optical quality factor of 1.7x10 5 allowed us to measure mechanical vibrations of the GOBLiT with mechanical quality factor 206 in air for the n=2 degenerate wineglass mode. Light was coupled into the resonator via a tapered optical fiber and used to sense mechanical motion of the GOBLiT. This result shows the viability of the toroidal-lipped GOBLiT for applications such as opto-mechanical gyroscopes.
