“…This phenomenon is well-studied, both theoretically and experimentally, for plane waves 33 and theoretically investigated for the beams comprising phase singularities 20,34,35 . In the experiment, the Talbot effect of the OAM-carrying beams was observed in the 1D case 31 , as well as for the two-dimensional configuration at the THz radiation 35,36 and near-infrared single photons 37 . In the 1D case 31 , the experimental intensity patterns were in the form of a periodic set of stripes, while for two-dimensional configuration there is an array of beams with a topological charge.…”
