We review recent works on optomechanics of optically trapped microspheres and nanoparticles in vacuum, which provide an ideal system for studying macroscopic quan-tum mechanics and ultrasensitive forc...
Dissipative Optomechanics in a Michelson--Sagnac Interferometer
Dissipative Optomechanics Michelson--Sagnac Interferometer optical element decay rate
2011/8/11
Abstract: Dissipative optomechanics studies the coupling of the motion of an optical element to the decay rate of a cavity. We propose and theoretically explore a realization of this system in the opt...
Abstract: We present a new micromechanical resonator designed for cavity optomechanics. We have used a micropillar geometry to obtain a high-frequency mechanical resonance with a low effective mass an...
