Research Projects

1. Coupled Optical Antenna Based Optoelectronic Device

In this project, we are studying the interactions between artificial nanostructures and colloidal quantum dots to control carrier generation in the quantum dots for advanced electro-optic imaging applications. This research project is funded by the Department of Defense.

 

2. Surface Plasmon Sensors

The surface electromagnetic wave in a metal nanostructure are extremely sensitive to its surface condition. We are studying characteristics of this surface wave in metal nanostructures nanostructures to create novel optical sensors. This is a multidisciplinary research project with the University of Texas at Arlington and Virginia Tech. NIH and NSF is jointly supporting this project.

 

3. Super-resolution Imaging System

The lateral resolution of a traditional optical microscope is fundamentally limited by the well-known Abbe diffraction limit. This goal of this project is to develop an interferometric imaging system to overcome the diffraction limit. This exploratory research is sponsored by the Interdisciplinary Research Grant (IRG) program from the Office of the Vice President for Research at NMSU.
