Claim of US Patent No. 10,558,027

1. A method of concentrating light by coupling light into a thin film waveguide arranged on a substrate via at least one of its parallel surfaces, the method comprising the step of exciting in the thin-film-waveguide at least one lateral guided mode having a node by scattering, diffraction or surface plasmon excitation of the incident light at a nanopatterned discontinuous excitation layer, the nanopatterned discontinuous excitation layer being in the thin-film-waveguide at a position of the node of the guided lateral mode.
