Temporal Signature of Bosonic Stimulation Induced by Dark Exciton in a Two-photon Pumped Polariton Condensate
Nadav Landau, Dmitry Panna, Sarit Feldman +4
Strongly-coupled light-matter exciton-polaritons constitute an on-chip solid-state platform where the macroscopic quantum phenomenon of condensation is not only achievable at eleva…
Two-photon pumped exciton-polariton condensation
Nadav Landau, Dmitry Panna, Sebastian Brodbeck +3
Two-photon absorption (TPA) allows accessing dark states of matter otherwise inaccessible to light, which serve as important building blocks for quantum information processing. In…
Polariton Laser in the Bardeen-Cooper-Schrieffer Regime
Jiaqi Hu, Zhaorong Wang, Seonghoon Kim +6
Microcavity exciton polariton systems can have a wide range of macroscopic quantum effects that may be turned into better photonic technologies. Polariton Bose-Einstein condensatio…
Emergence of micro-frequency comb via limit cycles in dissipatively coupled condensates
Seonghoon Kim, Yuri G. Rubo, Timothy C. H. Liew +4
Self-sustained oscillations, limit cycles, are a fundamental phenomenon unique to nonlinear dynamic systems of high-dimensional phase space. They enable understanding of a wide ran…
Photon number-resolved measurement of an exciton-polariton condensate
M. Klaas, E. Schlottmann, H. Flayac +10
We measure the full photon-number distribution emitted from a Bose condensate of microcavity exciton-polaritons confined in a micropillar cavity. The statistics are acquired by mea…
Observation of the transition from lasing driven by a bosonic to a fermionic reservoir in a GaAs quantum well microcavity
S. Brodbeck, H. Suchomel, M. Amthor +4
We show that, by monitoring the free carrier reservoir in a GaAs-based quantum well microcavity under nonresonant pulsed optical pumping, lasing supported by a fermionic reservoir…

Holger Suchomel, Sebastian Brodbeck, Timothy. C. H. Liew +6
Microcavity exciton polaritons are promising candidates to build a new generation of highly nonlinear and integrated optoelectronic devices. Such devices range from novel coherent…
Experimental verification of the very strong coupling regime in a GaAs quantum well microcavity
Sebastian Brodbeck, Simone De Liberato, Matthias Amthor +5
When the coupling between light and matter becomes comparable to the energy gap between different excited states they hybridize, leading to the appearance of a rich and complex phe…

We report the elliptically, close to circularly polarized lasing at and 1.522 eV from an AlAs/AlGaAs Bragg microcavity with 12 GaAs quantum wells in the active regi…
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…

The semiconductor polariton laser promises a new source of coherent light, which, compared to conventional semiconductor photon lasers, has input-energy threshold orders of magnitu…
