Revealing the dark side of a bright exciton polariton condensate
J. -M. Mènárd, C. Poellmann, M. Porer +5
Condensation of bosons causes spectacular phenomena such as superfluidity or superconductivity. Understanding the nature of the condensed particles is crucial for active control of…

Microcavity design for low threshold polariton condensation with ultrashort optical pulse excitation
C. Poellmann, U. Leierseder, E. Galopin +5
We present a microcavity structure with a shifted photonic stop-band to enable efficient non-resonant injection of a polariton condensate with spectrally broad femtosecond pulses.…
