Thermo-mechanical characterization of on-chip buckled dome Fabry-Perot microcavities
M. H. Bitarafan, H. Ramp, T. W. Allen +5
We report on the thermomechanical and thermal tuning properties of curved-mirror Fabry-Perot resonators, fabricated by the guided assembly of circular delamination buckles within a…
Optomechanics and thermometry of cryogenic silica microresonators
A. J. R. MacDonald, B. D. Hauer, X. Rojas +3
We present measurements of silica optomechanical resonators, known as bottle resonators, passively cooled in a cryogenic environment. These devices possess a suite of properties th…
Optical microscope and tapered fiber coupling apparatus for a dilution refrigerator
A. J. R. MacDonald, G. G. Popowich, B. D. Hauer +5
We have developed a system for tapered fiber measurements of optomechanical resonators inside a dilution refrigerator, which is compatible with both on- and off-chip devices. Our a…
Superfluid nanomechanical resonator for quantum nanofluidics
X. Rojas, J. P. Davis
We have developed a nanomechanical resonator, for which the motional degree of freedom is a superfluid 4He oscillating flow confined to precisely defined nanofluidic channels. It i…
Ultrasonic Interferometer for First-Sound Measurements of Confined Liquid 4He
X. Rojas, B. D. Hauer, A. J. R. MacDonald +3
We present a new technique for probing the properties of quantum fluids in restricted geometries. We have confined liquid 4He within microfluidic devices formed from glass wafers,…
