Dispersive optomechanics: a membrane inside a cavity
We present the results of theoretical and experimental studies of dispersively coupled (or ‘membrane in the middle’) optomechanical systems. We calculate the linear optical properties of a high finesse cavity containing a thin dielectric membrane. We focus on the cavity’s transmission, reflection and finesse as a function of the membrane’s position along the cavity axis and as a function of its...
متن کاملMicromanipulation transfer of membrane resonators for circuit optomechanics
A capacitive coupling between mechanical resonator and a microwave cavity enables readout and manipulation of the vibrations. We present a set-up to carry out such experiments with aluminum membranes fabricated as stamps and transferred in place with micromanipulation. The membrane is held in place by van der Waals forces, and is supported by three microscopic points. We measure the lowest mech...
متن کاملTunable Bistability in Hybrid Bose-Einstein Condensate Optomechanics
Cavity-optomechanics, a rapidly developing area of research, has made a remarkable progress. A stunning manifestation of optomechanical phenomena is in exploiting the mechanical effects of light to couple the optical degree of freedom with mechanical degree of freedom. In this report, we investigate the controlled bistable dynamics of such hybrid optomechanical system composed of cigar-shaped B...
متن کاملCryogenic optomechanics with a Si3N4 membrane and classical laser noise
We demonstrate a cryogenic optomechanical system comprising a flexible Si3N4 membrane placed at the center of a free-space optical cavity in a 400mK cryogenic environment. We observe a mechanical quality factor Q > 4× 106 for the 261 kHz fundamental drum-head mode of the membrane, and a cavity resonance halfwidth of 60 kHz. The optomechanical system therefore operates in the resolved sideband l...
متن کاملLaser optomechanics
Cavity optomechanics explores the interaction between optical field and mechanical motion. So far, this interaction has relied on the detuning between a passive optical resonator and an external pump laser. Here, we report a new scheme with mutual coupling between a mechanical oscillator supporting the mirror of a laser and the optical field generated by the laser itself. The optically active c...
