Short Description
We aim to develop and investigate numerical methods for simulating photonic cavities for quantum technology applications. In particular, we plan to research methods based on highly efficient rational approximation of the photonic response in the complex frequency plane. We will develop innovative frameworks based on the Adaptive Antoulas-Anderson (AAA) algorithm. These methods will allow to investigate and optimize photonic cavities with multiscale geometries, such as nanobeam cavities including 2D quantum materials. These are building blocks of quantum key distribution setups and other integrated quantum devices.
