Polarization tomography of photon pairs emitted by nonlinear metasurfaces with quasi-bound states in the continuum resonances
2024 Conference on Lasers and Electro-Optics, CLEO 2024
We use complete polarization tomography of photon pairs generated in semiconductor metasurfaces via spontaneous parametric down-conversion to show how bound states in the continuum resonances affect the polarization state of the emitted photons.
