Boyd Quantum Photonics Research Group

Boyd Rochester Laboratory Facilities

Dr. Robert Boyd has four fully outfitted research laboratories at the Institute of Optics of the
University of Rochester. These laboratories are each equipped with multiple 4’x8’x2’ (or larger)
optical tables and light-darkening safety currents, which facilitate the simultaneous operation of
multiple laboratory experiments. These laboratories contain all the necessary equipment to
conduct state-of-the-art experiments in the fields of nonlinear optics of new photonic materials,
quantum imaging, plasmonics, high capacity quantum key distribution, and nanophotonics.

The following is a list of the laser system which support this research effort:
