Coherent/decoherent coupling of excitations in molecular-plasmonic heterostructures — •Stephanie Cheylan¹, Hongdan Yan¹, Peter Lemmens¹, Meinhard Schilling², Andrey Bakin³, Johannes Ahrens⁴, and Martin Bröring⁴ — ¹IPKM, TU-BS, Braunschweig — ²EMG, TU-BS, Braunschweig — ³IHT, TU-BS, Braunschweig — ⁴IAAC, TU-BS, Braunschweig

We study the coherent coupling between plasmons of Au nanowire arrays and excitons of moleculare components, given by BODIPY and its derivative aza-BODIPY. The exciton energy of these two classes of molecules is tuned to match with different plasmonic modes. Different interactions are investigated depending on the morphology of the nanowire array and the energy of molecular excitons.
