Crosstalk of ring Airy Gaussian vortex beams disturbed by hazy scattering media and its suppression
Abstract:
The scattering medium significantly degrades the quality of the ring Airy Gaussian vortex beam (RAGVB) and induces crosstalk among orbital angular momentum (OAM) modes, thereby impairing the performance of OAM-based optical communication systems. In this study, we systematically investigate the effects of the scattering medium on the OAM spectral crosstalk in RAGVBs. Furthermore, we propose a correction scheme that combines the light intensity transport equation with a modified Gerchberg-Saxton phase retrieval algorithm (ITE-GS) to mitigate the impact of the scattering medium and ensure stable transmission of RAGVBs. These findings may have broad applications in optical communication, rotational sensing, and other related fields.
