Summary

• What is new: The introduction of astigmatism to enhance speckle-learned demultiplexing of OAM beams in optical communications.
• Why this is important: Fully exploiting the entire spectrum of OAM modes in optical communications has been challenging.
• What the research proposes: Using a tilted spherical convex lens to introduce astigmatism in far-field speckle patterns, allowing for better utilization of OAM beams.
• Results: Successful demonstration of an optical communication link encoded with OAM shift keying and OAM multiplexing, accurately decoded via speckle-learned demultiplexing.
