Coherent interaction between a single molecule and a plasmonic nanoantenna — •Johannes Zirkelbach¹, Benjamin Gmeiner¹, Tobias Utikal¹, Stephan Götzinger^1,2, and Vahid Sandoghdar^1,2 — 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].
