Opto-Mechanical Modal Spectroscopy: Opto-Excited Vibrations of a Micron-Scale On-Chip Resonator

Abstract

Radiation pressure is used to excite vibrational modes of an optical micro-cavity at GHz rates. Many spectral lines associated with high-order vibrational modes are measured. Perturbation of the cavity geometry is observed to induce splitting of the spectral lines. copy 2007 Optical Society of America OCIS codes: (230.1040) Acousto-optical devices: (300.6330) Spectroscopy, inelastic scattering including Raman.
