Abstract

Structured light beams with phase or polarization singularities reveal unique optical properties with numerous applications. Chiral nanostructures draw promising routes for enhancing singular optical signatures with new functionalities. Recently, near-field singular optical effects have been of interest in relation to surface plasmon (SP) vortices which have been shown to carry orbital angular momentum (OAM).
