Anomalous transient behavior from an inhomogeneous initial optical vortex density

Author: Roux, FS Date: Apr 2011 Inhomogeneous optical vortex densities can be produced in stochastic optical fields by a combination of coherent and incoherent superposition of speckle fields. During subsequent propagation, the inhomogeneity in the vortex density decays ... Read more
Coordinate invariance in stochastic singular optics

Author: Roux, FS Date: Nov 2013 The study of optical vortices in stochastic optical fields involves various quantities, including the vortex density and topological charge density, that are defined in terms of local expectation values of the distributions of optical vortices. ... Read more
Evolution of the optical vortex density in phase corrected speckle fields

Author: Roux, FS ; Chen, M Date: Sep 2010 In an attempt to understand the process whereby the phase modulation due to atmospheric turbulance causes phase singularities (also called optical vortices), the authors investigated the effect of phase perturbations in speckle beams. They ... Read more
Evolution of the scintillation index and the optical vortex density in speckle fields after removal of the least-squares phase

Author: Chen, M ; Roux, FS Date: Oct 2010 Knowledge of the behavior of stochastic optical fields can aid the understanding of the scintillation of light propagating through a turbulent medium. For this purpose, the authors perform a numerical investigation of the evolution of the ... Read more
Stochastic singular optics (Conference paper)

Author: Roux, FS Date: Sep 2014 The study of optical vortices in stochastic optical fields involves various quantities, including the vortex density and topological charge density, that are defined in terms of local expectation values of distributions of optical vortices. ... Read more
