Design challenges and guidelines for free-space optical communication links using orbital-angular-momentum multiplexing of multiple beams. (14th June 2016) - Willner, Alan E
Abstract: In this paper, recent studies on the potential challenges for an orbital angular momentum (OAM) multiplexing system were reviewed. The design guideline for a practical OAM multiplexing system were investigated in term of (i) the power loss due to the beam divergence and limited-size receiver, and (ii) the channel crosstalk due to the misalignment between the transmitter and receiver.
