Nanoscale Waveguide Schematic (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption The hybrid plasmon polariton (HPP) nanoscale waveguide consists of a semiconductor strip separated from a metallic surface by a low dielectric gap. Schematic shows HPP waveguide responding when a metal slit at the guide’s input end is illuminated.
