The optical vortex on a chip is of extreme importance for many applications in nanoscience, and as well-known, the chiral metallic nanostructures like plasmonic lenses (PVLs) can produce spin-dependent (PV) which governed by spin–orbit coupling. well-established nanophotonic theory various experimental demonstrations all show single PV mode one PVL, when excitation fixed. Here, counterintuitively, we report existence nontrivial deuterogenic PVs, besides predicted previously. We theoretically reveal general spin-to-orbit coupling experimentally demonstrate surprising multiple PVs PVL even excited fixed circularly polarized beam. This work provides deeper fundamental understanding dynamics near-field nanophotonics, promises to flexibly manipulate emerging vortex-based nanotechnologies quantum chip.
