My group's research focuses on novel materials and devices to exploit interactions of light with matter:

  1. Chalcogenide glass materials and devices for sensing and nonlinear optics;
  2. Light management in concentrated photovoltaics and thin film solar cells;
  3. On-chip magneto-optical isolation and nonreciprocal photonics;
  4. Photonic integration on unconventional substrates; and
  5. Materials and devices for infrared imaging, spectroscopy, and advanced manufacturing.
Ellen Swallow Richards, MIT’s first alumna, was the wife of Robert H. Richards, the first head of Course III.
