Refractometric sensing of Li salt with visible-light Si3N4 microdisk resonators
C. Doolin, P. Doolin, B. C. Lewis +1
We demonstrate aqueous refractive index sensing with 15 to 30 μm diameter silicon nitride microdisk resonators to detect small concentrations of Li salt. A dimpled-tapered fiber is…
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,…
Nonlinear optomechanics in the stationary regime
C. Doolin, B. D. Hauer, P. H. Kim +3
We have observed nonlinear transduction of the thermomechanical motion of a nanomechanical resonator when detected as laser transmission through a sideband unresolved optomechanica…
