Paper Abstract

In the paper, design of the phase-only mask enabling generation of variable superpositions of vortices is described and analyzed. A variability of the generated mixed vortex field is achieved by intensity modulation of an array of point sources illuminating the mask. A usability of the vortex superpositions for information encoding, transfer and decoding is also demonstrated. The optical setup prospective for application in free-space communications is proposed and experimentally tested.
