Welcome!

Our research group at UVA explores novel physics and applications of optical microresonators and optical frequency combs. Optical microresonators can confine optical energy in small dielectric structures, which enable optical power to build up for nonlinear optics effects. Optical microresonators have broad applications in sensing, nonlinear optics, optomechanics, and optical frequency combs. Our group explores both the soliton regime and the quantum regime of optical-microresonator-based frequency combs, and their applications in quantum computing, microwave photonics, and metrology.
