Abstract:
1. A waveguide structure for propagating a surface plasmon polariton, comprising: a plasmonic waveguide having two strip like structures of a first material positioned parallel to each other and a further strip like structure of a second material positioned between the two strip like structures of the first material, the first and second material being different materials selected from the group of a metal material and an isolating material, the two strip like structures of the first material being positioned at a fixed distance from each other, wherein the two strip like features of the first material and the further strip like structure of the second material of the plasmonic waveguide are present in a single layer of a CMOS processed substrate, wherein the first and second material of the waveguide structure comprises CMOS compatible materials in the form of deposited patterned layers and/or modified patterned layers of the substrate, wherein the two strip like features of the first material are part of a single deposited patterned layer and/or modified patterned layer, and a further plasmonic waveguide, the further plasmonic waveguide being oriented plan parallel to the single layer or perpendicular to the single layer.
