Perspective on using multiple orbital-angular-momentum beams for enhanced capacity in free-space optical communication links

Structured light has gained much interest in increasing communications capacity through the simultaneous transmission of multiple orthogonal beams. This paper gives a perspective on the current state of the art and future challenges, especially with regards to the use of multiple orbital angular mom...
