Opt Lett. 2021 Jul 01;46(13):3037-3040. doi: 10.1364/OL.427335.

We demonstrate an easy two-step maskless method for the fabrication of so-called compound fork-shaped gratings in nanomultilayer structures (NMLSs) based on chalcogenide glasses. Such elements allow one to generate different configurations of optical vortex (OV) beams with given topological...
