Abstract

Optical vortices [1,2] carry an annular spatial profile and an orbital angular momentum of (where ℓ is the topological charge) per photon owing to the phase singularity. In particular, optical vortices enable the creation of nanoscale cliiral 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.
