NanoPhotoNet-MPM: Physics-Informed Neural Surrogate for Inverse SPDC Design
A physics-informed neural surrogate framework combining an EigenmodeDeepONet transverse eigensolver, a deterministic physics conversion layer, and a CWE-PINN longitudinal propagator for inverse design of modal phase-matched biphoton quantum light sources in anisotropic monoclinic NbOCl2 waveguides.
