Abstract

Optical vortices [1,2] carry an annular spatial profile and an orbital angular momentum of ℓħ (where is the topological charge) per photon, owing to the phase singularity. In particular, optical vortices enable the creation of nanoscale chiral structures in various materials, such as azo-polymers [3,4], silicon, and metal. Such chiral nanostructures formation strongly desires compact visible vortex sources and their selective handedness (the sign of the topological charge) control.
