Abstract

We develop an ultrathin source of two-photon polarization Bell states based on an InGaP nonlinear metasurface. The metasurface facilitates a local optical resonance with a tailored angular dispersion, enabling the generation of polarization-entangled photon pairs through spontaneous parametric down conversion. This opens new possibilities for practical applications of integrated metasurfaces in advanced quantum technologies.
