Polarimetric Metagrating‐Assisted One‐Step Multi‐Dimensional Sensing Using a Vector Vortex Beam [PDF]

Nanophotonics
One‐step multidimensional sensing is realized by combining VVB probes with a polarimetric metagrating, where the full‐Stokes diffraction orders retrieve m‐dependent angular features and the polarization‐insensitive central order extracts l‐dependent radial‐intensity information. ABSTRACT Multidimensional optical sensing requires compact methods capable
