Metasurfaces consisting of nanoscale structures are underpinning new physical principles
for the creation and shaping of quantum states of light. Multiphoton states that are entangled …

The rapid development of optical metasurfaces, 2D ensembles of engineered
nanostructures, is presently underpinning a steady drive toward the miniaturization of many …

We reveal that strongly enhanced generation of photon pairs with narrow frequency spectra
and sharp angular correlations can be realised through spontaneous parametric down …

In this work, a doubly resonant photonic crystal (PhC) cavity is proposed to enhance second
harmonic generation (SHG) efficiency and photon pair generation rate (PGR). Through the …

We present the fundamental concepts for enhancing photon-pair generation through
spontaneous parametric downconversion in nonlinear dielectric metasurfaces. We show that …

The rapid development of metasurfaces-2D ensembles of engineered nanostructures-is
