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…
Lasing of Moiré Trapped MoSe/WSe Interlayer Excitons Coupled to a Nanocavity
Chenjiang Qian, Mirco Troue, Johannes Figueiredo +8
We report lasing of moiré trapped interlayer excitons (IXs) by integrating a pristine hBN-encapsulated MoSe/WSe heterobilayer into a high- () nanophotonic cavity.…
Effects of the linear polarization of polariton condensates in their propagation in codirectional couplers
Elena Rozas, Alexey Yulin, Johannes Beierlein +9
We report on the linear polarization of polariton condensates in a codirectional coupler that allows evanescent coupling between adjacent waveguides. We observe polarization-depend…
Spatial coherence of room-temperature monolayer WSe exciton-polaritons in a trap
Hangyong Shan, Lukas Lackner, Bo Han +16
The emergence of spatial and temporal coherence of light emitted from solid-state systems is a fundamental phenomenon, rooting in a plethora of microscopic processes. It is intrins…
Bloch Oscillations of Hybrid Light-Matter Particles in a Waveguide Array
Johannes Beierlein, Oleg. A. Egorov, Tristan H. Harder +6
Bloch oscillations are a phenomenon well known from quantum mechanics where electrons in a lattice experience an oscillatory motion in the presence of an electric field gradient. H…
