Surface Plasmon Tunable Filter and Spectrometer-on-a-Chip
Surface plasmon tunable filter (SPTF) is a new technology invented in Jet Propulsion Lab. When a white light is incident on a metal/air/metal structure, in certain condition, surface plasmon waves can be excited at one metal/air material interface; those photons in surface plasmon resonances wavelength range will be converted into the energy of free electrons in the metal than coupled into the other metal film, and re-radiate out the color light.
