Dark optical solitons: physics and applications
TL;DR: A detailed overview of the physics and applications of optical dark solitons can be found in this article, where the authors discuss the instability-induced dynamics of dark-solitons in the models of generalized (i.e., non-Kerr) optical nonlinearities.

TL;DR: In this paper, an isolated dark ring is created within a light beam, with an analytical description of the field, and a screw wave-front dislocation has a feature that the spatial structure of the wave front has the form of a helicoid around the dislocation axis.

TL;DR: The fabrication and characterization of a high-quality spiral phase plate is described as a device to generate optical vortices of low (3-5) specified charge at visible wavelengths and the reproducibility of the manufacturing process is excellent.
Journal ArticleDOI
Recent advances on optical vortex generation
TL;DR: In this paper, the authors summarized different approaches for optical vortex generation by discrete components and laser cavities, and highlighted the independent operation of these two different phases which leads to a multifunctional optical vortex beam generation and independent spin-orbit interaction.

Helical-wavefront laser beams produced with a spiral phaseplate
TL;DR: In this paper, a spiral phaseplate can convert a TEM00 laser beam into a helical wavefront beam with a phase singularity at its axis, and the diffractive-optical effect of the spiral phase plate is implemented by index matching a macroscopic structure in an optical immersion.

Astigmatic laser mode converters and transfer of orbital angular momentum
TL;DR: In this paper, a mode converter based on the Gouy phase was proposed to transform a Hermite-gaussian mode of arbitrarily high order to a Laguerre-Gaussian mode and vice versa.
Journal ArticleDOI
Optical Vortices and Their Propagation
TL;DR: In this paper, the free space propagation of an array of optical vortices nested in a smooth (Gaussian) beam is studied in the paraxial regime, and it is shown that their relative positions, as well as their positions within the host beam are invariant upon propagation.

Optics of light beams with screw dislocations
TL;DR: In this paper, the screw dislocations of different charges produced by diffraction on the computer-synthesized grating or by nonlinear processes of second- harmonic generation are experimentally studied and discussed.

Screw Dislocations in Light Wavefronts
TL;DR: In this paper, the screw dislocations of a phase surface are used as wavefronts of a monochromatic wave and a simple method for construction of the optical wavefront with an isolated screw dislocation is reported.
