Ultrasensitive optical magnetometry at the microscale
Stefan Forstner, Eoin Sheridan, Joachim Knittel +4
Recent advances in optical magnetometry have achieved record sensitivity at both macro- and nano-scale. Combined with high bandwidth and non-cryogenic operation, this has enabled m…
Ultra-broadband and sensitive cavity optomechanical magnetometry
Bei-Bei Li, George Brawley, Hamish Greenall +4
Magnetostrictive optomechanical cavities provide a new optically-readout approach to room temperature magnetometry. Here we report ultrasensitive and ultrahigh bandwidth cavity opt…
High bandwidth on-chip capacitive tuning of microtoroid resonators
Christopher G. Baker, Christiaan Bekker, David L. McAuslan +2
We report on the design, fabrication and characterization of silica microtoroid based cavity opto-electromechanical systems (COEMS). Electrodes patterned onto the microtoroid reson…
Microphotonic Forces From Superfluid Flow
D. L. McAuslan, G. I. Harris, C. Baker +4
In cavity optomechanics, radiation pressure and photothermal forces are widely utilized to cool and control micromechanical motion, with applications ranging from precision sensing…
Optomechanical magnetometry with a macroscopic resonator
Changqiu Yu, Jiri Janousek, Eoin Sheridan +5
We demonstrate a centimeter-scale optomechanical magnetometer based on a crystalline whispering gallery mode resonator. The large size of the resonator allows high magnetic field s…
Laser cooling and control of excitations in superfluid helium
G. I. Harris, D. L. McAuslan, E. Sheridan +3
Superfluidity is an emergent quantum phenomenon which arises due to strong interactions between elementary excitations in liquid helium. These excitations have been probed with gre…
