Angular-momentum nanometrology in an ultrathin plasmonic topological insulator film

Multiplexed vortex light beams are promising for optical communications, but efficient mode sorting is so far limited to bulk optics. Here the authors develop a scalable vortex beam sorter that uses a plasmonic topological insulator structure to spatially separate the modes to resolve them on a stan...
