Devices created and studied by our group members concentrate optical energy into nanoscale volume, enhancing nominally small effects such as the optical coupling of radiation pressure from single photons to the motion of mechanical nanoresonators. In the ultimate limit, even for a weak input consisting of only a single photon, these effects can significantly modify the linear response of a nanophotonic device, leading to fundamental studies and practical quantum technologies.

Silicon Photonic Spin-Optomechanical Sensors

Silicon Photonic Spin-Optomechanical Sensors We have recently demontrated nanocavity optomechanical devices based on silicon photonics which can detect sources of torque with unprecedented sensitivity. These structures are currently being used toprobe nanomagnetic phenomena and demomstrate magnetic field sensors with unique combination of spatial…
