Abstract Text:
Plasmonics is a very active research area dealing with fundamental studies of Surface Plasmon Polaritons (SPPs), and opening promising technological perspectives within nano-optics. SPPs are oscillations of surface electron charge density that exist at a metal/dielectric interface. Such oscillations are travelling waves with well-defined frequency, wave vector, and are evanescently confined in the perpendicular direction to the propagation. Even though, SPPs basic properties have been known for long by now, the relevance in nanophotonics applications has brought a renewed interest in such topic. In this work, experimental results of the coupling efficiency of light to SPPs is presented. The SPPs modes were excited at a polymer-metal interface. The measurements were made at different incidence excitation angles using a polymer edge nanostructure for SPP launching. The structure is similar to that used in dielectric-loaded surface plasmon polariton waveguides. The analysis of the coupling efficiency dependence might lead to a compensation solution for SPP propagation length losses.
