My research focuses on the controlled coupling of individual organic dye molecules to photonic circuitry made from dielectric waveguides with subwavelength cross sections. The long-term goal of the project is to generate and investigate polaritonic states formed by several molecules coupled via the waveguide circuitry.

Dominik Rattenbacher studied physics in the "Physics Advanced Programme" at the Universities of Erlangen and Regensburg from 2013 to 2018. After a research stay at the Ultrafast and Attosecond Science group of Prof. Wörner at ETH Zurich, he started his Master thesis on "Spectroscopic investigation of two molecules coupled via a dielectric waveguide" at the MPL. The work of his PHD thesis is a direct continuation of this project and aims at coupling several molecules efficiently via a nanophotonic circuit.
