Investigation of a Single Chiral Nano-Structure — •Paweł Woźniak1,2, Sarah Fritsch1,2, Peter Banzer1,2, Katja Höflich1, Silke Christiansen1,2, and Gerd Leuchs1,21Max Planck Institute for the Science of Light, Günther-Scharowsky-Str. 1, D-91058 Erlangen, Germany — 2Institute of Optics, Information and Photonics, University Erlangen-Nuremberg, Staudtstr. 7/B2, D-91052 Erlangen, Germany

Metamaterials built from chiral meta-atoms have attracted increasing interest in the last years. For instance, such materials can be used as broadband waveplates which sense the handedness of the impinging light beam. In our studies, we experimentally investigate the optical properties of single nano-scaled helices using different types of tightly focused polarization tailored light beams. The single three dimensional nanostructures are fabricated on an ITO-on-glass substrate using electron-beam-induced deposition (EBID) [1]. They consist of a composite material of gold nano-crystals (2-7 nm) embedded into a carbonaceous matrix. They are designed such that they have a diameter of only 50-200 nm with up to five helix pitches resulting in a resonant behavior in the visible wavelength range. We present first experimental results of our measurements on single nano-helices performed in transmission and reflection.
