Paper Abstract

We report our results on arrays of transparent metal coated wedges for plasmonic nanofocusing. FIB milling and chemical etching were used for the fabrication. FEM simulations were used to design the system. The design, fabrication and characterization of wedge structures are presented. The structure shows plasmonic properties in the optical spectral range, with excitation and propagation of surface plasmon polaritons at the wedge tip. The particular designs proposed allow the condensation of plasmonic waves at the wedge tips leading to the nanofocusing effects.
