Singular Optics: Singular Optics With Polychromatic Light

open access: yesOptics and Photonics News, 2002
The singular optics with polychromatic light was discussed. The spectral structure of light near phase singularities in the focal region of a spatially fully coherent but polychromatic, converging, spherical wave was studied. The analysis showed that the

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).

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.

Editorial: Singular and Correlation Optics

open access: yesFrontiers in Physics, 2021
Singularities in wave fields form a relatively young concept of wave physics originating from the seminal article by Nye and Berry. Initially, this concept seemed rather abstract and curious, but the development of laser optics has demonstrated the ...
