Optical communication system using Gaussian vortex beams.

J Opt Soc Am A Opt Image Sci Vis

Published: October 2020

We describe the details of an optical communication system using Gaussian vortex beams (GVBs). Our main focus will be on the detection strategy. The transmitter encodes the message symbols into the topological charges of the GVBs. Then the receiver implements a detection strategy based on the orthogonality of the GVBs. The graphical results obtained from the related theoretical derivation indicate that this detection strategy has almost no bounds. Thus, it is concluded that the performance of such a system can only be practically limited.
