Nonlocal incoherent solitons [PDF]
, 2004 We investigate the propagation of partially coherent beams in spatially nonlocal nonlinear media with a logarithmic type of nonlinearity. We derive analytical formulas for the evolution of the beam parameters and conditions for the formation of nonlocal ...

Photonics, 2021 In this paper, we present a method to independently control the field and irradiance statistics of a partially coherent beam. Prior techniques focus on generating optical field realizations whose ensemble-averaged autocorrelation matches a specified ...

Self-steering partially coherent beams
Scientific Reports, 2017 AbstractWe introduce a class of shape-invariant partially coherent beams with a moving guiding center which we term self-steering partially coherent beams. The guiding center of each such beam evolves along a straight line trajectory which can be engineered to make any angle with the x-axis.

Second-Order Statistics of Self-Splitting Structured Beams in Oceanic Turbulence
Photonics, 2023 Free-space optical communication is restricted by random media-stimulated beam degradation. However, partially coherent structured beams modulated by the coherence structure can potentially mitigate this negative effect. By employing the extended Huygens–

Wigner transform approach to dynamic-variable partially coherent laser beam characterization [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 1) Background: the modeling, characterization, transformation and propagation of high-power CW laser beams in optical (including fiberoptic) trains and in the atmosphere have become hot topics in laser science and engineering in the past few years ...

Frontiers in Physics, 2023 When analyzing the transmission characteristics of LEDs for long-distance lighting and communication applications, the light field is commonly assumed to be fully incoherent. However, in reality, the LED light source emits partially coherent light with a

Partially Coherent Flat-Topped Beam Generated by an Axicon
Applied Sciences, 2019 The intensity distribution of a partially coherent beam with a nonconventional correlation function, named the multi-Gaussian Schell-model (MGSM) beam, focused by an axicon was investigated in detail.

Coherent Patterning of Matter Waves with Subwavelength Localization [PDF]
, 2009 We propose the Subwavelength Localization via Adiabatic Passage (SLAP) technique to coherently achieve state-selective patterning of matter waves well beyond the diffraction limit.

Partially coherent fractional vortex beam
Optics Express, 2018 We introduce a new kind of partially coherent vortex (PCV) beam with fractional topological charge named partially coherent fractional vortex (PCFV) beam and derive the propagation formula for such beam passing through a stigmatic ABCD optical system with the help of the convolution method.
