Surface Optomechanics: Calculation of Love Surface Acoustic Waves on Microresonators
We calculate optomechanically excited Love waves on the surface of a silica whispering-gallery microresonator surrounded by air and pollutants. We show a method for sensing and distinguishing type or concentration of pollutant via frequency shift.
