Pump-power-driven mode switching in a microcavity device and its relation to Bose-Einstein condensation
H. A. M. Leymann, D. Vorberg, T. Lettau +8
We investigate the switching of the coherent emission mode of a bimodal microcavity device, occurring when the pump power is varied. We compare experimental data to theoretical res…
Exciton-Polariton Flows in Cross-Dimensional Junctions
K. Winkler, H. Flayac, S. Klembt +5
We study the nonequilibrium exciton-polariton condensation in 1D to 0D and 1D to 2D junctions by means of non-resonant spectroscopy. The shape of our potential landscape allows to…
Circular and Linear Photogalvanic Effects in Type-II GaSb/InAs Quantum Well Structures in the Inverted Regime
H. Plank, S. A. Tarasenko, T. Hummel +5
We report on the observation of photogalvanic effects induced by terahertz radiation in type-II GaSb/InAs quantum wells with inverted band order. Photocurrents are excited at obliq…
Visualising Berry phase and diabolical points in a quantum exciton-polariton billiard
E. Estrecho, T. Gao, S. Brodbeck +5
Diabolical points (degeneracies) can naturally occur in spectra of two-dimensional quantum systems and classical wave resonators due to simple symmetries. Geometric Berry phase is…
Uncovering dispersion properties in semiconductor waveguides to study photon-pair generation
K. Laiho, B. Pressl, A. Schlager +5
We investigate the dispersion properties of ridge Bragg-reflection waveguides to deduce their phasematching characteristics. These are crucial for exploiting them as sources of par…
