Abstract. In recent years, orbital angular momentum (OAM) optical communi-cation system has attracted much attention due to its larger channel capacity and stronger noise immunity. The light beam
Orbital angular momentum multiplexing is a physical layer method for multiplexing signals carried on electromagnetic waves using the orbital angular momentum (OAM) of the electromagnetic waves to distinguish between the different orthogonal signals. OAM is one of two forms of angular momentum of light; it is distinct from, and should not be confused with, light spin angular momentum. The latter offers only two orthogonal

Multiplexing multiple orbital angular momentum (OAM) channels enables high-capacity optical communication.
The field of OAM is fairly young, with the idea of vortex beams carrying OAM being first reported in a classic paper by L. Allen and colleagues in 1992 (see “Light Served with a Twist,” OPN, June 2017,
This allow it to become impractical in real time and threats the scalability of MDM in next generation optical communication system. For OAM
Light carries spin (polarization) and orbital angular momentum (OAM). We review recent work on the stable propagation and nonlinear properties of such states in fibers, which have spawned
