Anomalous dispersion via dissipative coupling in a quantum well exciton-polariton microcavity
DÄ brówka BiegaÅska, 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
DÄ brówka BiegaÅska, 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 $…
Coherence of a non-equilibrium polariton condensate across the interaction-mediated phase transition
P. Comaron, E. Estrecho, M. Wurdack +9
The emergence of spatial coherence in a confined two-dimensional Bose gas of exciton-polaritons with tuneable interactions offers a unique opportunity to explore the role of intera…
Narrow-linewidth exciton-polariton laser
Bianca Rae Fabricante, Mateusz Król, Matthias Wurdack +8
Exciton-polariton laser is a promising source of coherent light for low-energy applications due to its low-threshold operation. However, a detailed experimental study of its spectr…
