Abstract

The generation of multiple vortex cones using an annular aperture array and a spatial light modulator (SLM) is studied. The direct downscale imaging of an SLM on the surface of an annular aperture enables the direct-phase modulation of the annular aperture. It is experimentally demonstrated that the directphase modulation of an annular aperture array can control both the topological charge and the horizontal positions of multiple vortex cones simultaneously.
