TL;DR: In this paper, it was shown that the optically induced splitting of the exciton-polariton eigenstate, both in linear and circular polarizations, is responsible for the observed polarization effects.

TL;DR: In this paper, the spontaneous formation of a stochastic polarization in exciton-polariton Bose-Einstein condensates in planar microcavities under pulsed excitation was demonstrated.

TL;DR: In this paper, strong coupling of the whispering gallery modes with bulk excitons in semiconductor cylinders is demonstrated theoretically, and the strong coupling threshold is governed by the radiative decay rate of optical modes, which is analyzed as a function of the radius of the cylinder.

TL;DR: In this paper, the authors observed ballistic propagation of the excited polaritons as a ring spreading in real space, and the linear polarization degree P of the emission at the ring was found to oscillate as a function of the azimuthal angle θ and of time t according to P=sin(2θ)sin(ΩLTt∕2), where ΩLT is the longitudinal-transverse splitting of the exciton-polariton modes.

TL;DR: In this paper, a real-time observation of the crossover between photon and exciton-polariton lasing in a semiconductor microcavity is reported, where both phases are observed at different times after a high-power excitation pulse.
