Modematching for helical plasmonic resonators — •Thorsten Feichtner¹, Katja Höflich², and Bert Hecht¹ — ¹Nano- Optics & Biophotonics Group, Department of Experimental Physics 5, Röntgen Research Center for Complex Material Research (RCCM), Physics Institute, University of Würzburg, Am Hubland, D-97074 2Würzburg, Germany — ²Helmholtz Zentrum für Materialien und Energie Berlin, Hahn-Meitner-Platz 1, D-14109 Berlin, Germany

Mode-matching is a novel theoretical approach for the description of optical coupling between a plasmonic device and multiple emitters or receivers [1]. Here we apply the method to describe the far-field coupling of nanometer-sized metal helices [2] to circular polarized light, proving the viability and flexibility of mode-matching. We also show that a 1D model is sufficient to describe qualitatively the complex scattering behavior of the helical plasmonic nano resonator.
