Summary

• What is new: This research identifies a universal function that governs the coupling of photonic orbital angular momentum (OAM) modes through complex random media, a previously unexplored area.
• Why this is important: Structured light communication is hampered by intermodal crosstalk when passing through complex random media, such as Earth’s atmosphere.
• What the research proposes: The study proposes understanding and utilizing a universal function related to the ratio of the medium’s and the beam’s transverse correlation lengths to mitigate the effects of crosstalk.
• Results: Both numerical simulations and experimental results support the existence of this universal function, suggesting a new way to optimize structured light communication through random media.
