Shannon Entropy of Laguerre-Gaussian Correlated Schell-Model Beams in Underwater Turbulence

This study examines the evolution of Shannon entropy, a key measure of uncertainty and disorder, in a Laguerre-Gaussian correlated Schell-model (LGcSM) beam under ocean turbulence. We explore how the spatial coherence distribution of the LGcSM beam influences its Shannon entropy in both free space and ocean turbulent conditions. Our results show that tailoring the optical coherence distribution can significantly control spatial disorder, enabling the beam to restore order under turbulence. Furthermore, we analyze the impact of various ocean turbulence parameters on Shannon entropy evolution, offering a potential strategy to mitigate performance degradation in optical communication systems affected by turbulence.
