Vectorial optical fields (VOFs) exhibiting arbitrarily designed wave-fronts and polarization distributions are highly desired in photonics. To efficiently generate arbitrary VOFs, scientists in China proposed a generic approach based on metasurfaces exhibiting full-matrix yet inhomogeneous Jones-matrix distributions. Based on their strategy, efficient generations of complex VOFs in both far- and near-field were experimentally demonstrated in the NIR regime. The proposed meta-platform opens new avenues for diversified photonic applications, such as optical trapping and super-resolution imaging.
