Abstract
This paper gives a review for our recent progress on N-fold orbital angular momentum (OAM) multicasting links. By exploiting optimized complex phase pattern, the data information carried by an input Gaussian mode can be copied and delivered to multiple OAM modes which are distinguishable from each other owing to their own distinct spiral phase fronts. Experiment demonstration of 1-to-34 OAM multicasting, adaptive power-controllable OAM multicasting, and compensation of a distorted OAM multicasting link are presented.
