How to use the dispersion in the ${\chi }^{(3)}$ tensor for broadband generation of polarization-entangled photons

Valeria Vento, Francesco Ciccarello, Sakthi Pryia Amirtharaj +1

Polarization-entangled photon pairs are a widely used resource in quantum optics and technologies, and are often produced using a nonlinear process. Most sources based on spontaneo…
