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…
Exciton diffusion in two-dimensional chiral perovskites
Sophia Terres, Lucas Scalon, Julius Brunner +10
Two-dimensional (2D) organic-inorganic hybrid perovskites emerged as a versatile platform for light-emitting and photovol-taic applications due to their unique structural design an…
Anomalous dispersion via dissipative coupling in a quantum well exciton-polariton microcavity
Dąbrówka Biegańska, Maciej Pieczarka, Christian Schneider +3
Although energy level repulsion is typically observed in interacting quantum systems, non-Hermitian physics predicts the effect of level attraction, which occurs when significant e…
Optical properties and dynamics of direct and spatially and momentum indirect excitons in AlGaAs/AlAs quantum wells
Dąbrówka Biegańska, Maciej Pieczarka, Krzysztof Ryczko +5
We present an experimental study on optical properties and dynamics of direct and spatially and momentum indirect excitons in AlGaAs/AlAs quantum wells near the crossover between $…
Dynamic Phase Enabled Topological Mode Steering in Composite Su-Schrieffer-Heeger Waveguide Arrays
Min Tang, Chi Pang, Christian N. Saggau +10
Topological boundary states localize at interfaces whenever the interface implies a change of the associated topological invariant encoded in the geometric phase. The generically p…
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…
