Abstract

The pointing error (pointing deviation) of light beam is an important factor affecting the signal transmission quality of underwater optical communication system. Here we investigated the effects of weak turbulent seawater on the propagation of orbital angular momentum(OAM) modes carried by deflection Bessel Gaussian beams. The analytic expression of the received probability of the signal and crosstalk OAM mode was derived based on the theories of Rytov theory. The results show that smaller deflection has a significant effect on the improvement of signal received probability. And with the increase of the dissipation rate of the mean-squared temperature and the decrease of the rate of dissipation of kinetic energy per unit mass of fluid, the turbulence of seawater increases, and the influence of turbulence on the beam increases Our results also indicate that the received signal probability can be improved by use of deflection Bessel Gaussian beams with low OAM quantum number and long wavelength.
