Abstract
In recent years, orbital angular momentum (OAM) optical communication system has attracted much attention due to its larger channel capacity and stronger noise immunity. The light beam carrying OAM has infinite orthogonal characteristics and can make full use of spatial dimension, which provides a new idea for high-capacity communication. This paper outlines the basic theory of OAM and the development status of OAM optical communication, focusing on the modulation technology based on spatial light modulator (SLM) and the demodulation technology based on convolutional neural networks (CNN). Finally, the current challenges and future development trends of wireless optical OAM communication are discussed, being summarized and prospected to provide references for further research.
