What are plasmons?

Plasmons are coupled electromagnetic/electronic waves that occur inside and on the surface of metals and other materials. What makes plasmons of current interest is their ability to confine light to nanoscale regions--much smaller than the wavelength of light. At Duke, we are considering the use of plasmons for a variety of applications, from photonic networks to biosensors. This site is being designed to provide information on plasmonics activities here at Duke, as well as background information and highlights from other groups around the world.
