Structure of optical vortices.

چکیده
Helical modes of light can be focused into toroidal optical traps known as optical vortices, which are capable of localizing and applying torques to small volumes of matter. Measurements of optical vortices created with the dynamic holographic optical tweezer technique reveal an unsuspected dependence of their structure and angular momentum flux on their helicity. These measurements also provide evidence for a novel optical ratchet potential in practical optical vortices.

Optical phase singularities in detection of laser beam collimation.
Optical phase singularities, also called optical vortices, are known to have applications in various branches of optics. Here the role played by optical vortices in collimation testing is explained. Interference and a diffractive experimental setup in which the presence of an optical vortex permits collimation testing are presented. It is shown that the moire fringes that aid in collimation det...
متن کاملX-ray phase vortices: theory and experiment.
We review the current work on x-ray phase vortices. We explain the role of an x-ray vortex in phase recovery and speculate on its possible applications in other fields of x-ray optical research. We present our theoretical understanding of the structure of phase vortices and test these predictions against experiment. We present experimental observations of phase vortices with charge greater than...
متن کاملInterferometry with Vortices
Interference of optical beams with optical vortices is often encountered in singular optics. Since interferometry makes the phase observable by intensity measurement, it brings out a host of applications and helps to understand the optical vortex. In this article we present an optical vortex interferometer that can be used in optical testing and has the potential to increase the accuracy of mea...
متن کاملGeneration of lattice structures of optical vortices
We demonstrate experimentally the generation of square and hexagonal lattices of optical vortices and reveal their propagation in a saturable nonlinear medium. If the topological charges of the vortices have identical signs, the lattice exhibits rotation, whereas if their signs alternate between being the same and being opposite to each other, we observe stable propagation of the structures. In...
متن کاملOptical Vortex Filaments
This chapter examines the vortex core size and how it affects the propagation dynamics of neighboring optical vortices in the same beam. When the core is small compared to the distance between neighboring vortices, the vortices may be called vortex filaments. Such vortices have been found to exhibit unusual propagation dynamics such as rapid fluid-like vortex-vortex “effective interactions” [1,...
