Ghost Branch Photoluminescence From a Polariton Fluid Under Nonresonant Excitation
Maciej Pieczarka, Marcin Syperek, Åukasz Dusanowski +8
An expanding polariton condensate is investigated under pulsed nonresonant excitation with a small laser pump spot. Far above the condensation threshold we observe a pronounced inc…
Single vortex-antivortex pair in an exciton polariton condensate
Georgios Roumpos, Michael D. Fraser, Andreas Löffler +3
In a homogeneous two-dimensional system at non-zero temperature, although there can be no ordering of infinite range, a superfluid phase is predicted for a Bose liquid. The stabili…
Gain-induced trapping of microcavity exciton polariton condensates
Georgios Roumpos, Wolfgang H. Nitsche, Sven Hoefling +2
We have performed real and momentum space spectroscopy of exciton polariton condensates in a GaAs-based microcavity under non-resonant excitation with an intensity stabilized laser…
Stochastic Formation of Polariton Condensates in Two Degenerate Orbital States
Kenichiro Kusudo, Na Young Kim, Andreas Loeffler +3
We explore the exciton-polariton condensation in the two degenerate orbital states. In the honeycomb lattice potential, at the third band we have two degenerate vortex-antivortex l…
Atomically flat single-crystalline gold nanostructures for plasmonic nanocircuitry
Jer-Shing Huang, Victor Callegari, Peter Geisler +12
Deep subwavelength integration of high-definition plasmonic nanostructures is of key importance for the development of future optical nanocircuitry for high-speed communication, qu…
Higher order coherence of exciton-polariton condensates
Tomoyuki Horikiri, Paolo Schwendimann, Antonio Quattropani +3
The second and third order coherence functions of an exciton-polariton condensate is measured and compared to the theory. Contrary to an ideal photon…
