Optical Devices and Nanophotonics

Optical pump-probe experiments studying the nonlinear behavior of surface plasmon meta-materials.

The mission of nanophotonics research is to scale optical devices and components to their ultimate size limits. This usually involves designing near-field optical interactions that guide electromagnetic energy on a scale well below the diffraction limit. The group is currently involved in understanding the electro-optic properties of surface plasmon nanostructures using several numerical and experimental methods. The nanophotonics group also collaborates closely with material scientists (Dr. Knowlton, Hughes, Yurke) in exploring new sub-10 nm fabrication technique using single strand DNA as assembly scaffold.

Funding for this area of research is provided by NSF.
