Universal Function Approximation via Diffractive Optical Processors: Physical Limits, Error Bounds, and Learnability
arXiv:2608.04582v1 Announce Type: cross Abstract: We present a unified theoretical framework connecting classical universal approximation theory, Fourier-feature approximation, and diffractive optical processors. We show that phase-encoded diffractive processors implement finite Fourier-feature expansions whose mathema
