Deterministic Transferable Planar Dielectric Mirrors for Investigating Strong Light-Matter Coupling
Atanu Patra, Subhamoy Sahoo, Johannes Düreth +2
Optical cavities play a central role in photonic and quantum technologies by enhancing light-matter interactions. In semiconductor microcavities, achieving high quality (Q) factors…
Probing Local Topology in a Disordered Higher-Order Topological Insulator
Johannes Düreth, Simon Widmann, Philipp Gagel +13
Higher-order topology is prized for its ability to realize lower-dimensional boundary states which are stable beyond fine-tuning. However, disorder presents a failure mechanism tha…
Direct experimental access to the bulk band inversion in a topological metamaterial
Simon Widmann, Johannes Düreth, Siddhartha Dam +9
Topological phases in exciton-polaritons and other metamaterial platforms have attracted significant attention due to their flexibility as Hamiltonian simulators. In previous works…
Dynamically reconfigurable topological routing in nonlinear photonic systems
Stephan Wong, Simon Betzold, Sven Hofling +1
The propagation path of topologically protected states is bound to the interface between regions with different topology, and as such, the functionality of linear photonic devices…
Artificial Gauge Fields and Dimensions in a Polariton Hofstadter Ladder
Simon Widmann, Jonas Bellmann, Johannes Düreth +11
Artificial gauge fields allow uncharged particles to mimic the behavior of charged particles subjected to magnetic fields, providing a powerful platform for exploring topological p…
Hybrid confinement techniques for polariton simulators

Exciton-polariton III-V semiconductor microcavities provide a robust platform for emulating complex Hamiltonians, enabling topological photonics and quantum simulation for advanced…
Enwrapped Perylene Bisimide Enables Room Temperature Polariton Lasing and Photonic Lattices
Dominik Horneber, Johannes Düreth, Tim Schembri +5
Perylene bisimides (PBIs) are organic dyes with photoluminescence quantum yields (PLQY) close to unity in solution and great thermal and photo-chemical stability. These features al…
Topological Optical Waveguiding of Exciton-Polariton Condensates
Johannes Beierlein, Oleg A. Egorov, Philipp Gagel +9
One-dimensional models with topological non-trivial band structures are a simple and effective way to study novel and exciting concepts in topological photonics. In this work we ar…
An electrically pumped topological polariton laser
Philipp Gagel, Oleg A. Egorov, Franciszek Dzimira +9
With a seminal work of Raghu and Haldane in 2008, concepts of topology have been successfully introduced in a wide range of optical systems, emulating specific lattice Hamiltonians…
Dirac Cones and Room Temperature Polariton Lasing Evidenced in an Organic Honeycomb Lattice
Simon Betzold, Johannes Düreth, Marco Dusel +6
Artificial one- and two-dimensional lattices have emerged as a powerful platform for the emulation of lattice Hamiltonians, the fundamental study of collective many-body effects, a…
Polarized and Un-Polarized Emission from a Single Emitter in a Bullseye Resonator
Giora Peniakov, Quirin Buchinger, Mohamed Helal +12
We present polarized |S|=0.990.01, and unpolarized |S|=0.030.01 emission from a single emitter embedded in a single, cylindrically symmetric device design. We show that t…
Optical properties of circular Bragg gratings with labyrinth geometry to enable electrical contacts
Quirin Buchinger, Simon Betzold, Sven Höfling +1
We present an optical study of various device designs for electrically contactable circular Bragg grating cavities in labyrinth geometries. To create an electrical connection betwe…
