Stochastic singular optics

Proceedings of SPIE, 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 distributions of optical vortices. For stochastic optical fields that are inhomogeneous or not normally distributed, these local quantities often ...

Dynamic singular optics

Proceedings of SPIE, 2008
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).

Singularity screening in generic optical fields

Optics Letters, 2015
We 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.

Polarization singularities in optical lattices

Optics Letters, 2004
Polarization 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).

Nonlinear singular optics

Journal of Optics, 1998
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.

Singular optical phenomena in nature

SPIE Proceedings, 2008
Optical singularities serve as scientific landmarks in the topological landscape of light patterns. These curious features exhibit conservation properties and unique diffraction patterns that are finding increasing importance in many branches of modern optics.
