Advances in nano-fabrication and new materials continue to enable novel ways of controlling the creation, propagation and trapping of light in wavelength-scale structures. We engage in cutting-edge research on a broad range of exciting and innovative areas at the frontier of photonics and quantum optics, focusing on both fundamental physics and the practical applications of these concepts to technology.

At Princeton, we have ongoing efforts from discovering novel ways of performing high-speed optical signal and image processing to designing high-efficiency optical devices such as efficient light-emitting diodes, nonlinear frequency converters, photonic crystals, solar absorbers, compact coherent light sources, single-photon sources, and quantum simulators. We also explore fundamental aspects of light-matter interactions including Casimir forces, quantum many-body physics with coupled light-matter systems, and dynamics and control of quantum emitters.
