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. For stochastic optical fields that are inhomogeneous or not normally distributed, these local quantities often ...

This work started the dynamic singular optics, or real-time topological dynamics of developing singular light fields. We have used the system "laser beam → photorefractive crystal LiNbO 3 : Fe" which generates slowly developing scalar or vector random scattered singular light field (speckle patterns).

The physical background of singular optics dealing with phase singularities in light waves is reported as a new chapter in modern optics. A review of the current status of nonlinear singular optics is presented.

Polarization singularities in optical lattices
Optics Letters, 2004Polarization singularities are shown to be unavoidable features of three-dimensional optical lattices. These singularities take the form of lines of circular polarization, C lines, and lines of linear polarization, L lines. The polarization figures surrounding a C line (L line) rotate about the line with winding number +/-1/2 (+/-1).

Singularity screening in generic optical fields
Optics Letters, 2015We revisit the widely studied subject of screening in optical fields by topological charges and show that screening does not depend on charge ordering. Instead, for an array of N charges, screening requires that the variance of the charge fluctuations be small compared to N.

Möbius strips with one, two, three, and four, half-twists are shown to be generic features of three-dimensional (nonparaxial) elliptically polarized light. The geometry and topology of these unusual singularities is described and the multitude of winding numbers that characterize their structures is enumerated; probabilities for the appearance of ...
