Optics and photonics research spans a huge range of disciplines ranging from communications, biomedical instruments and devices, nanolithography and information processing. A subset of currently-funded research areas are: optofluidics, high-power semiconductor lasers, mid-infrared sources, silicon nanophotonics, light forces at the nanoscale, chip-scale interconnects, sub-diffraction lithography, polymeric optical materials, unconventional imaging and sensing, femtosecond laser nanofabrication, photonic crystals, optical metamaterials, plasmonics, wavefront coded imaging, 3D microscopy, antenna-based solar cells, terahertz-wave detectors, new energy technologies, high-temperature optoelectronics, nanofabrication, optical computing, signal processing, FR photonics, GaAs devices, and fiber optics.
Optics research in the ECEE department is part of the nanostructures and optics research area (see http://nanoandoptics.colorado.edu/ and also the larger, campus-wide program with over 50 faculty and 3 Nobels, as described more fully here: http://www.colorado.edu/optics/.
