Substrate for the generation of surface plasmons and surface plasmon polaritons by means of an excitation radiation, method for the production of the substrate, and uses of the substrate
The invention is directed to a substrate for generating surface plasmons (SPs) and surface plasmon polaritons (SPPs) by means of an excitation radiation, wherein the substrate has a carrier layer and a coating with gold or silver. A surface of the carrier layer is provided with identical surface structures arranged in an array of rows and columns. The surface structures are recesses with an elongate shape which are arranged with a first periodicity (PH) and with a second periodicity (PV) in direction of the rows and orthogonal to the direction of the rows, respectively. The invention is further directed to a method for the production of the substrate and to uses of the substrate.
