Polarization changes in a partially coherent radially polarized doughnut beam through turbulent ocean

Changes in polarization properties of partially polarized, partially coherent vectorial cosh-Gaussian beams propagating in oceanic turbulence

“…However, for a partially coherent radially polarized doughnut beam, the polarization properties only approach constant values in the far-field zone. [13] The effects of turbulence parameters for the ChG beam are: as ε increases, the amplitudes of polarization properties become greater, the range of variation along the z-axis increases, and the position of their peaks becomes further from the source plane. As the values of χ T or w increase, the polarization properties change more slowly, the amplitudes decrease, and the position of their peaks become slightly closer to the source Downloaded by [Northeastern University] at 15:19 03 January 2015 …”

“…Recently, a few papers have also appeared on the polarization changes of laser beams in oceanic turbulence and biological tissues. [11][12][13][14] It was found that even though the power spectrum of refractive index fluctuation has a very similar structure for random media, the polarization characteristics of beams traveling in these media are qualitatively different. To the best of our knowledge, only Gaussian Schell-mode beams and partially coherent radially polarized doughnut beams passing through oceanic turbulence have been studied.…”
