“…Studies on the propagation characteristics of beam-like fields in atmospheric turbulence are of important because of their direct applications in communication and sensing systems, the statistical properties of various laser beams propagating in the atmospheric turbulence have been investigated extensively [23][24][25][26][27][28][29][30][31][32][33]. A generalized model for the power spectrum characterizing atmospheric turbulence at various altitudes is known to have form [34]…”

We introduce a novel class of planar random source producing far fields with multi-ring-shaped average intensity patterns by modeling the source degree of coherence, and confirm that such sources are physically genuine. Further, we derive the analytical expressions for the cross-spectral density (CSD) function of the beam-like fields generated by the novel source propagating in free space and in a linear isotropic random medium, and analyze the evolution of the spectral density and the state of coherence. It is shown that at some distance from the source the spectral density of the propagating beam in free space takes on the shape-invariant multi-ring profile, and the number of rings and intensity profiles of the beams can be flexibly adjusted by changing the source parameters. However, in atmospheric turbulence, we find that at sufficiently large distances from the source, the multi-ring profiles are destroyed by the medium, even if it remains such for intermediate distances from the source.

“…Partially coherent vector beams characterized by a crossspectral density matrix (CSDM) [1] have aroused a wealthy of concerns due to their wide applications in optical communications, sensing and optical imaging [2][3][4][5][6][7][8][9][10][11][12][13][14]. In early years, most of the studies are focused on the conventional electromagnetic (EM) Gaussian Schell-model (GSM) [2] type.…”

We consider a class of specular or anti-specular vector beams, by illuminating stochastic vector beams into a prism-based wavefront-folding interferometer. Such transform is applied to various genuine model input beams, and then the properties of the resulting fields are discussed. Numerical results show that the specular nature of these vector fields not only creates sharp internal intensities, but also produces novel polarization patterns with oscillations or a central dip on the DOP-profile. Such optical characterizes can be flexibly modulated by the correlation structure of the source. We also suggest that the specular transform could be efficiently employed in developing novel partially coherent vector beams.

“…Several authors have investigated the effects of turbulence and the partially coherent source on the polarization of electromagnetic Gaussian Schell-mode (EGSM) beams propagation in atmosphere [1][2][3][4]. Tang et al propose a coherent multilevel polarization shift keying (MPOLSK) modulation scheme using the spatial diversity detection in a free-space optical (FSO) turbulence channel [5].…”
