I am a Professor and Head of the Chair of Experimental Physics I (EP) at the Julius-Maximilians-Universität Würzburg. I completed my habilitation in Experimental Physics in 2024, focusing on topological photonics and hybrid light-matter systems. My research explores how topological protection, well known from solid-state physics through phenomena such as the Quantum Hall and Quantum Spin Hall effects, can be transferred to photonic platforms. A key achievement of my group has been the realization of the first topological insulator for exciton-polaritons, hybrid quasiparticles formed from strong coupling between light and matter. This system offers unique opportunities to investigate novel many-body physics and quantum-coherent phenomena. In addition, we are working on semiconductor-based topological lasers, exceptional-point sensors, and other technologically relevant implementations of topological photonic structures.
Keywords: Quantum Photonics, Optical Spectroscopy, Light-matter Interactions in Semiconductors, Topological Effects in Photonic Systems, Epitaxy, Technology and Design of Microcavities, Exciton-Polaritons in Lattices, Novel Semiconductor Laser Designs, Novel 2D Semiconductor Materials
We are interested in the properties of individual optical micro-resonators and lasers as well as in their coupling with one another. Coupled optical resonator network and lattices are used to realized intricate optical band structures, emulating e.g. graphene physics in an optical system. By precisely tailoring the coupling properties we can realize topological non-trivial structures. We are then able to study the unique properties and the exciting potential of topological polaritons and topological lasers. Here, we are working within the Würzburg-Dresden cluster of excellency ctd.qmat. The platforms used for the realization of our samples range from group III-V semiconductirs such as GaAs to fluorescent proteins and transition metal dichalcogenides.
We constantly offer Bachelor and Master theses dealing with a relevant subtopic of the above mentioned projects.
Here are some examples:
- Polariton propagation in honeycomb lattices and nanoribbons
- Optical study of light-matter interaction in organic mCherry/eGFP microcavities
- Design and interface optimization of topological VCSEL lasers
You are kindly invited to send an email and I will try to find a project that can meet your interest. After that, we can discuss a possible project face-to-face or via zoom.
