The objective of the project is to investigate and apply numerical methods for the simulation of chiral light-matter interaction in nanostructures. The main goal is the development of contour integration based methods and their application to topical devices for photonic quantum technology.

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.
