Data underlying the publication: Optical Control of the Polarization State of a Polariton Condensate in a Bound State in the Continuum

The data underlying all figures of the associated manuscript about polarization control in a polariton laser. We investigated the emission properties of a polariton condensate under different pump geometries. We show that we can control the polarization of the condensate above lasing threshold. The core part of the data consists of images of an imaging spectrometer of a Fourier microscope showing angle resolved emission spectra (theta_x vs wavelength and theta_x vs theta_y) of the sample under different excitation fluences and geometries. Besides that there is the polarization data of the emission, data from RCWA simulations and Gross Pitaevski simulations.
