What Is Plasmonics?

Plasmons are an interaction between free electrons in a metallic material and electromagnetic radiation. Surface plasmons are plasmons that are confined to travel along the interface between a metallic material and a dielectric material. These surface waves can, through gratings, surface defects or prisms, couple electromagnetic radiation that is not bound to the surface (i.e. photons).

Plasmonics is an extremely broad field of study. Its applications vary from integrated optics on silicon microchips to enhancing absorption in state-of-the-art solar cells to sensing individual molecules of biohazardous materials. Our group has continuing projects in these areas as well as others.
