Enhanced generation of angle correlated photon-pairs in nonlinear metasurfaces

Enhanced generation of angle correlated photon-pairs in nonlinear metasurfaces

We reveal that strongly enhanced generation of photon pairs with narrow frequency spectra and sharp angular correlations can be realised through spontaneous parametric down-conversion in metasurfaces. This is facilitated by creating meta-gratings through nano-structuring of nonlinear films of sub-wa...
