POLARIZE 2 (IMAGE) Rice University Caption Circularly polarized light delivered at a particular angle to C-shaped gold nanoparticles produced a plasmonic response unlike any discovered before, according to Rice University researchers. When the incident-polarized light was switched from left-handed (blue) to right-handed (green) and back, the light from the plasmons switched almost completely on and off.
