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. Examples of projects are listed below:
Impurities in diamond are one of the most promising qubits for quantum information processing. They have been used already in proof-of-principle quantum optics experiments, and if they can be incorporated into nanophotonic devices it will be possible to build practical…
