We derive the detection limits of SAW resulting from Brillouin scattering in a WGR. We calculate the absolute concentration limits for detection of chemicals in fluids surrounding the WGR. Give general equations for velocity, linewidth, and detectabi

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.

Stimulated Brillouin scattering recently allowed experimental excitation of surface acoustic resonances in micro-devices, enabling vibration at rates in the range of 50 MHz to 12 GHz. The experimental availability of such mechanical whispering galler

We describe and experimentally demonstrate an optomechanical oscillator where light drives a surface mechanical mode of a spherical resonator, using a combination of photoelastic scattering and optical electrostriction. These oscillators are shown to

Stimulated Brillouin interaction between sound and light, known to be the strongest optical nonlinearity common to all amorphous and crystalline dielectrics, has been widely studied in fibres and bulk materials but rarely in optical microresonators.

We analyze circumferentially circulating mechanical whispering-gallery modes [WGM] resonating in a micron scaled silica sphere. We recently showed that such modes can be excited optically [1]. A variety of modes are calculated in which the deformatio

We experimentally demonstrate excitation by light of a mechanical Rayleigh surface mode. The acoustical mode is small in volume and high in mechanical Q, related to the small material dissipation for such waves and to the unique geometry in which the

We experimentally demonstrate the excitation of a mechanical Rayleigh surface mode through optical electrostriction in a silica microsphere resonator. These modes have applications in optomechanical photonic oscillators and surface acoustic wave base
