Abstract

Based on the extended Huygens–Fresnel principle and the second-order moments of the Wigner distribution function, propagation properties of radially polarized partially coherent beam in the oceanic turbulence are investigated. An analytical formula for the propagation factors (M² -factors) of partially coherent one-dimensional radially polarized beams in turbulent ocean is derived. The intensity distribution, degree of polarization and beam characteristic parameters of radially polarized partially coherent beam in turbulent ocean are numerically described in detail. It is shown that the oceanic turbulence parameters and the initial coherence length have significant influence on the degree of polarization and coherence for radially polarized partially coherent beams, and such beam is depolarized on propagation. As the value of the oceanic turbulence parameters (χT or w) increases and the coherence length of the beam decreases, the normalized M² -factor increases more rapidly. The results will be useful in long-distance free-space optical communications.
