Welcome to the Nanostructured Optoelectronics Group |
 |
Our research is focused on the development of quantum
cascade lasers, systems for chemical sensing and microscopy,
tunable plasmonic components and metamaterials operating in the
mid-infrared and THz spectral range. Details are provided in the
'Research' section.
Our work is currently supported by two NSF grants, an
AFOSR Young Investigator Program Grant, the Robert A. Welch Foundation,
and the Texas Board of Higher Education Norman Hackerman Advanced Research Program Award.
