Cavity optomechanical device
We are interested in the physics and engineering of nanophotonic devices in the context of quantum information science, metrology, communications, and sensing. We use nanofabrication technology to develop engineered geometries that strongly enhance light-matter interactions, such as parametric nonlinear optical processes, coupling to quantum emitters, and acousto-optic effects. We study the basic device-level physics and tailor devices for specific applications, and our research generally involves computational modeling, nanofabrication, and optoelectronic and quantum photonic characterization. Recent topics have included quantum frequency conversion, single-photon and entangled-photon generation, microresonator frequency combs, optical parametric oscillators, and cavity electro-optomechanical transducers.
More generally, nanophotonic systems offer us the ability to study interesting physics in a controllable way, using platforms that are inherently suitable for the development of new technologies. Our labs are at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD, and the Joint Quantum Institute at the University of Maryland in College Park.
