/CrOCl heterostructure exhibits strong polarization sensitivity across a broad spectral range from 405 to 1064 nm, with an anisotropy ratio up to ∼8. This performance supports polarization-resolved single-pixel imaging and near-infrared polarized optical communication. Our results demonstrate that symmetry-breaking-induced anisotropy engineering provides a powerful strategy for high-performance, broadband, and polarization-sensitive photodetection, offering promising opportunities for next-generation photonic information technologies.
