Rising complexity of the OAM beam structure as a way to a higher data capacity
Andrey Pryamikov
Abstract
Standard vortex beams carrying different OAM (optical angular momentum) modes can provide independent communication channels for information transmission. However, they are unable to reach the capacity limit of a communication channel due to a rapid divergence of the beams with high values of the OAM order. The solution can be found by using multi-vortex geometric beams.
