Femtosecond Laser Fabricated Components for Guiding and Focussing of Surface Plasmon Polaritons — •Sven Passinger, Carsten Reinhardt, and Boris N. Chichkov — Laser Zentrum Hannover e.V., Hollerithallee 8, 30419 Hannover

In this contribution, we study applications of two-photon polymerization (2PP) technique for the fabrication of dielectric structures on metal films, which can be used for guiding and manipulation of surface plasmon polaritons (SPPs). Dielectric SPP components, e.g. waveguides, bends and splitters are fabricated. SPP properties of these structures are investigated by scanning near-field optical microscopy (SNOM), demonstrating guiding and reflection of SPPs by polymer lines. SPP excitation on dielectric ridges and point structures is observed by far-field microscopy. Recent results on the focussing of SPPs and on the fabrication and characterization of metallic SPP-structures and components on dielectric substrates will be presented.
