Two-Level System Damping in a Quasi-One-Dimensional Optomechanical Resonator
B. D. Hauer, P. H. Kim, C. Doolin +2
Nanomechanical resonators have demonstrated great potential for use as versatile tools in a number of emerging quantum technologies. For such applications, the performance of these…
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…
Time-Resolved Mass Sensing of a Molecular Adsorbate Nonuniformly Distributed Along a Nanomechnical String
T. S. Biswas, Jin Xu, N. Miriyala +4
We show that the particular distribution of mass deposited on the surface of a nanomechanical resonator can be estimated by tracking the evolution of the device's resonance frequen…
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…
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…
Multidimensional optomechanical cantilevers for high frequency atomic force microscopy
C. Doolin, P. H. Kim, B. D. Hauer +2
High-frequency atomic force microscopy has enabled extraordinary new science through large bandwidth, high speed measurements of atomic and molecular structures. However, tradition…
A general procedure for thermomechanical calibration of nano/micro-mechanical resonators
B. D. Hauer, C. Doolin, K. S. D. Beach +1
We provide a detailed description of a general procedure by which a nano/micro-mechanical resonator can be calibrated using its thermal motion. A brief introduction to the equation…
Nanoscale Torsional Optomechanics
P. H. Kim, C. Doolin, B. D. Hauer +4
Optomechanical transduction is demonstrated for nanoscale torsional resonators evanescently coupled to optical microdisk whispering gallery mode resonators. The on-chip, integrated…
Dissipation Mechanisms in Thermomechanically Driven Silicon Nitride Nanostrings
A. Suhel, B. D. Hauer, T. S. Biswas +2
High-stress silicon nitride nanostrings are a promising system for sensing applications because of their ultra-high mechanical quality factors (Qs). By performing thermomechanical…
