Computational Nano Optics

Welcome to the homepage of the Computational Nano Optics research group at Zuse Institute Berlin!

CNO research group, 2024

The main focus in our research group is on investigation and application of numerical methods for simulating light-matter interactions on the nanoscale. An emphasis of research is on adaptive finite-element methods for solving Maxwell's equations. These developments are strongly interlinked to various collaborations with partners from academic, fundamental research and with partners from the industry.
