Multimode radiation pressure actuation of a mechanical resonator using a spatial mode sorter
Morgan E. Choi, Daniel Allepuz-Requena, Diego Torres-Barajas +2
Multimode optomechanical scattering is ubiquitous in free-space imaging protocols, but its radiation pressure counterpart is challenging to detect with extended objects. Here we de…
Dual mass milligram-scale torsion oscillator for vibration-free optomechanical sensing
Jack Manley, Thomas Bsaibes, Charles A. Condos +3
Chip-scale optomechanical devices are driving the miniaturization of inertial sensors and next generation fundamental physics experiments. However, precision at the theoretical lim…
Nanofabricated torsion pendulums for tabletop gravity experiments
Jack Manley, Charles A. Condos, Zachary Fegley +5
Measurement of mutual gravitation on laboratory scales is an outstanding challenge and a prerequisite to probing theories of quantum gravity. A leading technology in tabletop gravi…
Lithographically Defined SiN Torsional Pendulum
Thomas Bsaibes, Charles Condos, Jack Manley +3
Torsion pendulums provide an opportunity to trap large masses in a potential weak enough to explore two-body gravitation. Cooled to, and then released from a ground state, weak qua…
Optimal single-mode squeezing for beam displacement sensing
Wenhua He, Christos N. Gagatsos, Dalziel J. Wilson +1
Estimation of an optical beam's transverse displacement is a canonical imaging problem fundamental to numerous optical imaging and sensing tasks. Quantum enhancements to the measur…
Quantum limited imaging of a nanomechanical resonator with a spatial mode sorter
Morgan Choi, Christian Pluchar, Wenhua He +2
We explore the use of a spatial mode sorter to image a nanomechanical resonator, with the goal of studying the quantum limits of active imaging and extending the toolbox for optome…
Quantum-limited optical lever measurement of a torsion oscillator
Christian M. Pluchar, Aman R. Agrawal, Dalziel J. Wilson
The optical lever is a precision displacement sensor with broad applications. In principle, it can track the motion of a mechanical oscillator with added noise at the Standard Quan…
Imaging-based Quantum Optomechanics
Christian M. Pluchar, Wenhua He, Jack Manley +3
In active imaging protocols, information about an object is encoded into the spatial mode of a scattered photon. Recently the quantum limits of active imaging have been explored wi…
Focusing membrane metamirrors for integrated cavity optomechanics
A. R. Agrawal, J. Manley, D. Allepuz-Requena +1
We have realized a suspended, high-reflectivity focusing metamirror ( cm, ) by non-periodic photonic crystal patterning of a SiN memb…
Optimum classical beam position sensing
Wenhua He, Christos N. Gagatsos, Dalziel J. Wilson +1
Beam displacement measurements are widely used in optical sensing and communications; however, their performance is affected by numerous intrinsic and extrinsic factors including b…
Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
Suppression of extraneous thermal noise in cavity optomechanics
Yi Zhao, Dalziel J. Wilson, Kang-Kuen Ni +1
Extraneous thermal motion can limit displacement sensitivity and radiation pressure effects, such as optical cooling, in a cavity-optomechanical system. Here we present an active n…
