Key Points

Develop a geometric parameterization framework using neural networks to optimize freeform nanophotonic devices while satisfying complex fabrication and design constraints.
Introduced Neuroshaper, an overparameterized analytic neural network framework designed to model multi-scalar, freeform geometries within a smoothed optimization space.
Evaluated the framework's ability to execute topology manipulation and enforce geometric constraints across diverse nanophotonic architectures using numerical modeling and experimental fabrication.
Local constraint enforcement within the neural parameterization reliably produced coordinated, global modifications in overall device morphology.
Numerical and physical demonstrations confirmed effective optimization and manufacturability across a wide variety of nanophotonic device designs.
