Researchers have developed a theoretical framework that connects universal approximation theory with diffractive optical processors. This framework demonstrates how phase-encoded diffractive processors can implement finite Fourier-feature expansions, with their physical realizability dependent on optimized spatially varying coherent point-spread functions. The analysis provides error bounds separating various contributions, establishes scaling relationships for approximation complexity, and derives limits based on photon budget and throughput. AI
