Nonparaxial Propagation of Bessel Correlated Vortex Beams in Free Space

open access: yesMicromachines, 2022
The nonparaxial propagation of partially coherent beams carrying vortices in free space is investigated using the method of decomposition of the incident field into coherent diffraction-free modes.

Propagation of partially coherent light through a light pipe

open access: yesOptics Express, 2013
In laser projection applications, laser light modules are often combined with rotating diffusers in order to reduce the appearance of speckle on the projection screen. The rotation of a diffuser in a laser beam generates a beam of partially coherent light.

Mutual optical intensity propagation through non-ideal two-dimensional mirrors

open access: yesJournal of Synchrotron Radiation, 2023
The mutual optical intensity (MOI) model is a partially coherent radiation propagation tool that can sequentially simulate beamline optics and provide beam intensity, local degree of coherence and phase distribution at any location along a beamline. This

Discrete solitons and soliton-induced dislocations in partially-coherent photonic lattices

open access: yes, 2004
We investigate the interaction between a light beam and a two-dimensional photonic lattice that is photo-induced in a photorefractive crystal using partially coherent light.

A Scalar Wigner Theory for Polarized Light in Nonlinear Kerr Media [PDF]

open access: yes, 2012
A scalar Wigner distribution function for describing polarized light is proposed in analogy with the treatment of spin variables in quantum kinetic theory.

Effects of Atmospheric Turbulence on Lensless Ghost Imaging with Partially Coherent Light

open access: yesApplied Sciences, 2018
Ghost imaging with partially coherent light through two kinds of atmospheric turbulences: monostatic turbulence and bistatic turbulence, is studied, both theoretically and experimentally.

Scattering of Partially Coherent Vector Beams by a Deterministic Medium Having Parity-Time Symmetry

open access: yesPhotonics, 2022
We study the scattering properties of the partially coherent vector beams with the deterministic media having the classic symmetric and parity-time (PT) symmetric scattering potential functions.

Partially coherent conical refraction promises new counter-intuitive phenomena

open access: yesScientific Reports, 2022
In this paper, we extend the paraxial conical refraction model to the case of the partially coherent light using the unified optical coherence theory. We demonstrate the decomposition of conical refraction correlation functions into well-known conical ...
