摘要

Abstract

Simultaneous and continuous control over polarization and wavelength—two orthogonal and information-rich degrees of freedom—remains a central challenge in metasurface photonics

long hindered by intrinsic dispersion constraints and structural degeneracy. Here

we customize continuous polarization–wavelength mapping through a nonlocal metasurface platform that decouples birefringent evolution from structural dispersion. We achieve programmable

spectrally resolved polarization shaping across the broadband mid-infrared regime by introducing an equivalent nonlocal Jones matrix formalism and a dimension-interlaced vectorial diffraction neural network. This framework enables fully continuous and arbitrarily prescribed mapping across the joint polarization–wavelength space—beyond the capabilities of segmented or interleaved metasurface designs. We experimentally demonstrate non-degenerate multicolor vectorial holography

broadband achromatic imaging

and arbitrary elliptical polarization multiplexing with high fidelity and minimal crosstalk

maintaining strong channel isolation. Our results establish a scalable route toward continuous-domain photonic encoding

offering a powerful foundation for ultracompact optical communication

vectorial information encryption

and high-dimensional light-field processing.
