## Description

- description: "We propose a simple scheme of degenerate spontaneous parametric down-conversion
    (SPDC) in nonlinear metasurfaces or photonic crystal slabs with quasi-guided modes.
    \  \r\nIt employs a band crossing between even- and odd-parity quasi-guided mode
    bands inside the light cone (above the light line) and a selection rule in the
    conversion efficiency of the SPDC.   \r\nThe efficiency can be evaluated fully
    classically via the inverse process of noncollinear second-harmonic generation
    (SHG). As a toy model, we study the SPDC and SHG in a monolayer of noncentrosymmetric
    spheres and confirm that the scenario works well to enhance the SPDC.  "
