Abstract
Using orbital angular momentum (OAM) of optics can effectively increase the rate of information transmission of optical communication system. The basic concepts and main characteristics of OAM are introduced; the basic principles and typical systems of the OAM-based free space optical communication are overviewed. In addition, the corresponding key techniques are analyzed. Based on the which, the potential applications and developing trends of the OAM-based free space optical communication are also forecasted.
