We present a nonlinear metasurface with engineered symmetry facilitating an orders-of-magnitude enhancement of photon-pair generation and tunable entanglement through hyperbolic phase matching of spontaneous parametric down-conversion via multi-ple extended bound states in the continuum.

Abstract
We present a nonlinear metasurface with engineered symmetry facilitating an orders-of-magnitude enhancement of photon-pair generation and tunable entanglement through hyperbolic phase matching of spontaneous parametric down-conversion via multi-ple extended bound states in the continuum.File in questo prodotto:
