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.

本数据集支撑关联手稿中所有关于极化激元激光器（polariton laser）偏振调控的配图数据。我们研究了不同泵浦几何构型下极化激元凝聚体（polariton condensate）的发射特性，并证明可在激射阈值以上调控该凝聚体的偏振态。数据集的核心内容为傅里叶显微镜（Fourier microscope）配套成像光谱仪采集的图像，展示了样品在不同激发通量与激发几何构型下的角分辨发射光谱（angle resolved emission spectra），具体包含θ_x与波长的对应关系、θ_x与θ_y的对应关系。此外，数据集还包含发射偏振特性数据、严格耦合波分析（RCWA）模拟数据以及格罗斯-皮塔耶夫斯基（Gross-Pitaevskii）模拟数据。
