Abstract

We study the impacts of anisotropic turbulence on the bandwidth-limited orbital angular momentum (OAM) mode of partially coherent modified Bessel correlated beam propagation in oceanic turbulence. In a paraxial link, a power model of the bandwidth-limited OAM mode is established. We find that small-scale eddies of turbulence are an important factor that affects the power of the bandwidth-limited OAM mode transfer in a region of strong salinity fluctuation. By choosing the mode carrying lower OAM quantum number, we can transfer OAM information more efficiently, and by utilizing OAM modes with large energy level difference between modes, one can achieve multichannel communication.
