Abstract
An embodiment of the present invention relates to a photon-to-plasmon coupler for converting photons to plasmons or vice versa, said photon-to-plasmon coupler comprising a photonic waveguide for guiding photons, a plasmonic waveguide for guiding plasmons, and two plasmonic strip waveguides, each of said two plasmonic strip waveguides being connected to said plasmonic waveguide and embracing an end section of the photonic waveguide such that each of said plasmonic strip waveguides is optically coupled to the end section of the photonic waveguide.
