On the Twistability of Partially Coherent, Schell-Model Sources

Photonics
In this paper, the problem of assessing the twistability of a given bona fide cross-spectral density is tackled for the class of Schell-model sources, whose shift-invariant degree of coherence is represented by a real and symmetric function, denoted as μ(

Shaping partially coherent light by the coherent mode decomposition

Optics Express
The coherence properties of light are essential when it comes to its modulation, and light of partial coherence in particular demands special attention compared to fully coherent light. Designs for the latter have been favored by the compact platforms driving research into the manipulation of light at the microscale and below, such as photonic crystals,

Effects of residual coherence on the scintillation of a partially coherent beam

Optics Express, 2019
Recent results show that partially coherent beams (PCB) can be conveniently generated in a multimode fiber and modulated with data at gigabit per second rates, which makes them attractive for free-space optical communication through turbulent atmosphere. An important feature of these realistic beams in contrast to model ones is the presence of residual

Coherent properties of partially coherent vortex beam with nonuniform polarization propagating in turbulent atmosphere

Results in Physics
The spectral degree of coherence (SDOC) evolution of partially coherent vortex beam with radially and azimuthally polarized (RPV and APV) beams in atmospheric turbulence have been studied and the results indicate that SDOC distribution will gradually ...
