Vector Hermite-Gaussian correlated Schell-model beam.
TLDR
The behaviors of a vector HGCSM beam on propagation are quite different from those of a conventional vector partially coherent beam with uniform SOP or non-uniform SOP, and modulating the structures of the correlation functions cannot only modulate the intensity distribution, but also the state of polarization, the degree of polarization and the polarization singularities of a partially coherent vector beam on propagate.Citations

Generation of perfect vortex and vector beams based on Pancharatnam-Berry phase elements
TL;DR: In this article, a planar Pancharatnam-berry (PB) phase element was proposed to replace all the elements required to obtain the perfect vortex beam for integrated optical communication and micromanipulation systems.

Generation of Partially Coherent Beams
TL;DR: Partially coherent beams with a prescribed phase, state of polarization, and degree of coherence display many extraordinary propagation properties and are preferred in many applications, such as particle trapping, free-space optical communications, remote sensing, optical imaging, material thermal processing, image transformation, and optical encryption as discussed by the authors.

Experimental generation of optical coherence lattices
TL;DR: In this article, the authors report experimental generation and measurement of recently introduced optical coherence lattices and show theoretically that information can be encoded into and, in principle, recovered from the lattice degree of coherence.

Generation of vector partially coherent optical sources using phase-only spatial light modulators
TL;DR: In this article, the authors control both shape and coherence using liquid-crystal spatial light modulators, and can produce two different classes of PCBs using the same simple optical setup.

Unified theory of coherence and polarization of random electromagnetic beams
TL;DR: In this article, a unified theory of coherence and polarization of random electromagnetic beams is presented, which brings out clearly the intimate relationship which exists between these two phenomena and which makes it possible to predict the changes in the state of polarization of a partially coherent electromagnetic beam on propagation.

Change of polarization of light beams on propagation in free space
TL;DR: In this article, it was shown by use of a simple model that in general the state of polarization of a light beam generated by a partially coherent source changes as the beam propagates in free space.

Propagation characteristics of partially coherent beams with spatially varying correlations
Hanna Lajunen,Toni Saastamoinen +1 more
TL;DR: It is shown that mathematically simple modifications in the coherence function of conventional Gaussian Schell-model beams lead to partially coherent fields with extraordinary free-space propagation characteristics, such as locally sharpened and laterally shifted intensity maxima.
