Review Description

The transmission capacity of optical wireless communication systems has approached the Shannon limit, and the emergence of orbital angular momentum (OAM), as a lateral new space dimension resource, can exponentially improve the capacity and spectral efficiency of optical wireless communication networks. Adopting technologies of OAMrelated can provide a potential solution for the realization of ultrahigh speed and high capacity cross-scene optical communication in the future. On the basis of comparing and summarizing the relevant research results of OAM at domestic and overseas, this paper introduces the research work of OAM technology in the field of optical wireless communication in Xi'an University of Technology, which is mainly divided into the space generation, propagation characteristics, separation detection and application of OAM beams. Finally, the future development trend and prospect of OAM technology in the field of optical wireless communication are foreseen, which provides new thoughts and reference values for the subsequent researchers to explore in this field.
