A class of partially coherent beams carrying optical vortices.
نویسنده
چکیده
A new class of partially coherent beams with a separable phase, which carry optical vortices, is introduced. It is shown that any member of the class can be represented as an incoherent superposition of fully coherent Laguerre-Gauss modes of arbitrary order, with the same azimuthal mode index. The free-space propagation properties of such partially coherent beams are studied analytically, and their M2 quality factor is investigated numerically.

Spatial correlation vortices in partially coherent light: theory
Coherent optical beams may contain optical vortices that are characterized by a dark core and a well-defined azimuthally harmonic phase.1,2 In contrast, different points in a spatially incoherent beam are uncorrelated, and the phase structure of an optical vortex is ill defined. In the transitional regime of partially coherent light, one should take the statistical properties of light into acco...
متن کاملTopological reactions of correlation functions in partially coherent electromagnetic beams.
It was recently shown that so-called coherence vortices, singularities of the two-point correlation function, generally occur in partially coherent electromagnetic beams. We study the three-dimensional structure of these singularities and show that in successive cross sections of a beam a rich variety of topological reactions takes place. These reactions involve, apart from vortices, the creati...

By analysis of the far-field cross-correlation function (CCF) of partially coherent optical beams, we demonstrate an implicit rule that the number of ring dislocations (dark zones) of the far-field CCF is equal to the original topological charge of an optical vortex rendered partially coherent. This novel link between an optical vortex and its correlation singularity may offer an efficient meth...
متن کاملCoherence vortices in Mie scattered nonparaxial partially coherent beams.
We have previously demonstrated that Mie scattering of partially coherent plane waves can create coherence vortices, namely screw-type dislocations in the phase of the spectral degree of coherence. However, plane waves are an idealization and in practice, optical beams are often much closer to reality. Thus, in this paper, we consider coherence vortices created by Mie scattering of partially co...
متن کاملOptical Vortices and Vortex Solitons
Optical vortices are phase singularities nested in electromagnetic waves that constitute a fascinating source of phenomena in the physics of light and display deep similarities to their close relatives, quantized vortices in superfluids and Bose-Einstein condensates. We present a brief overview of the major advances in the study of optical vortices in different types of nonlinear media, with em...
