   Welcome to the Nanostructured Optoelectronics Group

Our current research interests include giant nonlinear optical effects in metamaterials, quantum cascade lasers, and other engineered and/or low-dimensional structures, sub-wavelength resolution microscopy in mid- and far-infrared, development and application of mid-IR and THz radiation sources and detectors, and plasmonic devices.

Our work is supported by AFOSR, ARO, DARPA, DOE, NSF, the Robert A. Welch Foundation, and the Texas Board of Higher Education Norman Hackerman Advanced Research Program.
