22 September 2007 Surface plasmon waveguiding and detection: dielectric-loaded metal surfaces

Dielectric thin films on a metal surface are an efficient means in terms of effective index contrast to realize optical elements for surface plasmon (SPs). We show that laterally structured thin films can on one hand be applied as SP lenses or prisms. On the other hand, they can be applied as SP waveguides, including bends and couplers.
