Polariton Lasing in Micropillars With One Micrometer Diameter and Position-Dependent Spectroscopy of Polaritonic Molecules
U. Czopak, M. Prilmüller, C. Schneider +2
Microcavity polaritons are bosonic light-matter particles that can emit coherent radiation without electronic population inversion via bosonic scattering. This phenomenon, known as…
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…
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…
Realization of all-optical vortex switching in exciton-polariton condensates
Xuekai Ma, Bernd Berger, Marc Assmann +5
Vortices are topological objects representing the circular motion of a fluid. With their additional degree of freedom, the 'vorticity', they have been widely investigated in many p…
Observation of gain-pinned dissipative solitons in a microcavity laser
Maciej Pieczarka, Dario Poletti, Christian Schneider +4
We demonstrate an experimental approach to create dissipative solitons in a microcavity laser. In particular, we shape the spatial gain profile of a quasi-one-dimensional microcavi…
Integration of atomically thin layers of transition metal dichalcogenides into high-Q, monolithic Bragg-cavities - an experimental platform for the enhancement of optical interaction in 2D-materials
Heiko Knopf, Nils Lundt, Tobias Bucher +8
We demonstrate a new approach to integrate single layer MoSeR2R and WSeR2R flakes into monolithic all-dielectric planar high-quality micro-cavities. These distributed-Bragg-reflect…
