All-optical linear polarization engineering in single and coupled exciton-polariton condensates
I. Gnusov, H. Sigurdsson, J. Toepfer +3
We demonstrate all-optical linear polarization control of exciton-polariton condensates in anisotropic elliptical optical traps. The cavity inherent TE-TM splitting lifts the groun…
Engineering photon statistics in a spinor polariton condensate
Stepan Baryshev, Anton V. Zasedatelev, Helgi Sigurdsson +4
We implement full polarization tomography on the photon correlations in a spinor exciton-polariton condensate. Our measurements reveal condensate pseudospin mean-field dynamics spa…
Coherence Revivals of a Spinor Polariton Condensate from Self-induced Larmor Precession
Alexis Askitopoulos, Helgi Sigurdsson, Ivan Gnusov +4
First order coherence measurements of a polariton condensate, reveal a regime where the condensate pseudo-spin precesses persistently within the driving optical pulse. Within a sin…
Optical orientation, polarization pinning, and depolarization dynamics in optically confined polariton condensates
Ivan Gnusov, Helgi Sigurdsson, Stepan Baryshev +3
We investigate the optical orientation, polarization pinning, and depolarization of optically confined semiconductor exciton-polariton condensates. We perform a complete mapping of…
