Propagation of optical coherence lattices in oceanic turbulence

Based on the extended Huygens-Fresnel principle, an analytical expression for the cross-spectral density of optical coherence lattices (OCL) in oceanic turbulence is derived. With the help of this expression, we investigate the propagation of OCL in oceanic turbulence. In order to increase underwater optical communication distance, we investigated the effects of source parameters, such as lattices constant, wavelength and beam width, on intensity distribution of OCL in oceanic turbulence. Results indicate that the light intensity received by receiver increases with the increase of lattice constant, the increase of beam width and the decrease of wavelength, which may have some potential applications in underwater optical communication.
