We plan to investigate the coupling of quantum dot single photon sources and other sources to experimentally realizable chiral nanoresonators. However, resonant photonic nanostructures typically support a large number of eigenmodes with complex properties, including electromagnetic (e-m) chirality density, quality-factor and mode volume. The interaction of light sources with such multimodal resonators needs to be accurately quantified for interpreting experimental results and for design purposes. For achieving near unity coupling efficiency, the various experimentally accessible parameters of the experimental setups need to be optimized.

Research results of this project include the investigation of long- and short-ranged chiral, electromagnetic interactions in plasmonic nano-assemblies [1, 2, 4, 5] as well as the investigation of coupled quantum dot – waveguide systems [3]. A typical, resonant near field distribution in a chiral nanoplasmonic setup [1] is shown in Figure 1.
