Coherent interaction between a single molecule and a plasmonic nanoantenna — •Johannes Zirkelbach1, Benjamin Gmeiner1, Tobias Utikal1, Stephan Götzinger1,2, and Vahid Sandoghdar1,2 — 1Max Planck Institute for the Science of Light (MPL), D-91058 Erlangen, Germany — 2Department of Physics, Friedrich-Alexander-University of Erlangen-Nürnberg, D-91058 Erlangen, Germany
We report on the coherent interaction of light with a coupled system consisting of a single quantum emitter and a plasmonic nanostructure. Here, we combine cryogenic high-resolution spectroscopy with localization microscopy to study single molecules in the vicinity of isolated plasmonic nanostructures embedded in a thin organic matrix. We discuss the spectral and spatial behavior of the extinction spectra recorded from the composite molecule-antenna system, leading to Fano profiles in the far-field interference signal. Future experiments will aim to observe transparency (cloaking) and ultrastrong absorption [1].
