Fig. 4

Coherence and polarization properties of the cooperative exciton-polariton condensation. a linearly polarization-resolved measurements below (blue dots) and above (red dots) Pth in the polar plot. The degrees of polarization are 9% and 83%, respectively. b Top, schematic of the Michelson interferometer setup. Bottom, illustration of the left and right symmetrically interfered images. c Typical interferogram for the angle-resolved PL spectra below and above the threshold. d Zoomed-in figures for the yellow dashed squares in c at the condensate state
