Room temperature topological polariton laser in an organic lattice
Marco Dusel, Simon Betzold, Tristan. H. Harder +7
Interacting bosonic particles in artificial lattices have proven to be a powerful tool for the investigation of exotic phases of matter as well as phenomena resulting from non-triv…
Entangled photon pairs from quantum dots embedded in a self-aligned cavity
Laia Ginés, Carlo Pepe, Junior Gonzales +4
We introduce a scalable photonic platform that enables efficient generation of entangled photon pairs from a semiconductor quantum dot. Our system, which is based on a self-aligned…
Direct Generation of Radially Polarized Vector Vortex Beam with an Exciton-Polariton Laser
Jiaqi Hu, Seonghoon Kim, Christian Schneider +2
Vector vortex beams are a class of optical beams with singularities in their space-variant polarization. Vector vortex beam lasers have applications in many areas including imaging…

We study the magneto-transport and magneto-electroluminescence properties of purely n-doped GaAs/AlGaAs resonant tunneling diodes with an InGaAs q…
Four-wave mixing dynamics of a strongly coupled quantum-dot--microcavity system driven by up to 20 photons
Daniel Groll, Daniel Wigger, Kevin Jürgens +6
The Jaynes-Cummings (JC) model represents one of the simplest ways in which single qubits can interact with single photon modes, leading to profound quantum phenomena like superpos…
Formation dynamics of exciton polariton vortices created by non-resonant annular pumping
Bernd Berger, Daniel Schmidt, Xuekai Ma +4
We study the spontaneous formation of exciton polariton vortices in an all-optical non-resonantly excited annular trap, which is formed by ring-shaped subpicosecond laser pulses. S…
Impact of the energetic landscape on polariton condensates propagation along a coupler
E. Rozas, J. Beierlein, A. Yulin +10
Polariton condensates propagation is strongly dependent on the particular energy landscape the particles are moving upon, in which the geometry of the pathway laid for their moveme…
Propagative oscillations in co-directional polariton waveguide couplers
