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

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 spontaneous parametric down-conversion have relatively narrow optical bandwidths because the pump, signal, and idler frequencies m...
