Helicity Sorting of Photons: A Spin Optical Device — •Enno Krauss¹, Gary Razinskas¹, Dominik Koeck¹, Swen Grossmann¹, and Bert Hecht^1,2 — ¹NanoOptics & Biophotonics Group, Experimentelle Physik 5, Physikalisches Institut, Universität Würzburg, Am Hubland, 97074 Würzburg, Germany — ²Röntgen Research Center for Complex Material Systems (RCCM), Am Hubland, 97074 Würzburg, Germany

Spin optics adds an additional degree of freedom and therefore promises new functionalities in optical nanocircuits in analogy to spintronics. Here we study experimentally and theoretically spin-optical devices, so-called photon helicity sorters, based on "birefractive" propagation in a plasmonic two-wire transmission line. We study the mechanism that leads to spin-orbit coupling in these devices including the role of a geometrical phase.
