3D photonic model systems for topological effects and quantum-optical analogies — •Christina Jörg — Department of Physics and Research Center OPTIMAS, RPTU Kaiserslautern-Landau

I will present our research on topological photonics and beyond using waveguide arrays and photonic crystals fabricated through 3D micro-printing. These photonic structures serve as model systems for fundamental studies, providing a versatile platform to emulate electronic phenomena found in condensed matter. By replicating electronic band structures, topological states, and quantum-optical effects, these systems not only deepen our understanding of established physics but also pave the way for discovering phenomena beyond what has been envisioned in electronic systems.

I will provide an overview of our recent work, which includes the use of higher orbital modes for quantum simulations, employing Kerr-nonlinearity to mimic mean-field interaction effects, and exploring higher-dimensional systems through synthetic dimensions.

Keywords: waveguide lattices; direct laser writing; nonlinear optics; orbital angular momentum
