Singular optics in coherence theory

Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing, 2004
Recent work has extended the field of singular optics by considering the phase singularities of two-point correlation functions. We describe some results from this work and how such ‘coherence singularities’ relate to the traditional coherent phase singularities.

Optical M��bius Singularities

2008
M bius 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 ...

Applications of Correlation Singular Optics

2019
Applications of coherent singular optics have developed mainly due to progress in nanotechnologies that focus on the problem of manipulation of nano-objects and control of their parameters. An opaque particle falling into the center of a scalar vortex is captured due to the difference in light pressure at the center and at the periphery of the vortex ...

Introduction to Linear Singular Optics

2009
Propagation of coherent radiation through inhomogeneous media with random fluctuations of local optical characteristics results in the formation of an optical wave that is characterized by random temporal and spatial distributions of its parameters such as intensity, phase, and, in general cases, its state of polarization. The fields formed in this way
