Dissipative and Dispersive Optomechanics in a Nanocavity Torque Sensor

Sensors in optical cavities can be used for measuring acceleration, fields, and particles. New research reveals a record sensitivity for detecting small amounts of torque within optical cavities, useful for detecting magnetic fields.

Single-Crystal Diamond Nanobeam Waveguide Optomechanics

Optomechanical devices sensitively transduce and actuate motion of nanomechanical structures using light. Single--crystal diamond promises to improve the performance of optomechanical devices, while also providing opportunities to interface nanomechanics with diamond color center spins and related quantum technologies. Here we demonstrate dissipative waveguide--optomechanical coupling exceeding 35 GHz/nm to diamond nanobeams supporting both optical waveguide modes and mechanical resonances, and use this optomechanical coupling to measure nanobeam displacement with a sensitivity of
