Surface plasmon micro- and nano-optics.
We report the experimental realization of key elements of a two-dimensional optics based on surface plasmon polaritons (SPPs). Local SPP sources, Bragg mirrors and beamsplitters were lithographically built from silver nanostructures. The SPP fields were imaged by detecting the fluorescence of molecules that act as local probes of the SPP near-field intensity.
