Zusammenfassung:
We experimentally and theoretically study the controlled coupling
between localized and delocalized surface plasmon modes supported by a
multilayer metallic photonic crystal slab. The model system to
visualize the interaction phenomena consists of a gold nanowire grating
and a spatially separated homogeneous silver film. We show that
plasmon-plasmon coupling leads to drastic modification of the optical
properties in dependence on the chosen geometrical parameters. Strong
coupling and plasmon hybridization can be clearly observed. The
numerical calculations reveal excellent agreement with the experiments.
