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 ...

Dark soliton stripes (DSS’s) and grids were recently discovered in the cross-section of a laser beam [1] which propagates through a self-defocusing medium. Now we find that a dark soliton stripe can spawn optical vortex pairs of opposite topological charge when subjected to transverse modulations whose period exceeds the soliton size.

Composite optical vortices may form when two or more beams interfere. Using analytical and numerical techniques, we describe the motion of these optical phase singularities as the relative phase or amplitude of two interfering collinear nonconcentric beams is varied.

Spatiotemporal Optical Vortices
2023Light beams carrying orbital angular momentum (OAM) have become a mainstay of optical science and technology. In these beams, well-known examples of which are the Laguerre-Gaussian (LG_pm ) and Bessel-Gaussian (BG_m ) beams, the OAM vector points parallel or anti-parallel to propagation, and is associated with a phase winding 2πm in the plane ...

Plasmonic tomography of optical vortices
Optics Letters, 2010We present a method for analyzing the wavefront of optical vortices that does not involve interferometry but rather uses surface plasmon polaritons (SPPs). We employ a subwavelength slit in a gold film to cut slices from an optical vortex beam and measure the diffraction of the generated SPPs by scattering them off a second slit.

Femtosecond Optical Vortices in Air
Physical Review Letters, 2005We examine the robustness of ultrashort optical vortices propagating freely in the atmosphere. We first approximate the stability regions of femtosecond spinning pulses as a function of their topological charge. Next, we numerically demonstrate that atmospheric optical vortices are capable of conveying high power levels in air over hundreds of meters ...

Quasi-monochromatic optical vortices
Proceedings of CAOL'2003. 1st International Conference on Advanced Optoelectronics and Lasers. Jontly with 1st Workshop on Precision Oscillations in Electronics and Optics (IEEE Cat. No.03EX715), 2004The propagation of a circularly polarized singular beam through a single-axis crystal is accompanied by the appearance of additional singularities in the polarization structure of the beam field. These vector singularities combine to form concentric umbilic lines-degenerate umbilic point of the star type, thus significantly changing the entire ...

Elliptic perfect optical vortices
Optik, 2018Abstract We generalize the concept of perfect optical vortices, studying the elliptic perfect optical vortices (EPOVs), which also have diameters independent on the topological charge. A pure-phase diffractive optical element is proposed for efficient generation of such EPOV.

Propagation invariant optical vortices
Frontiers in Optics, 2003The most known propagation invariant optical fields (PIOFs) are the Bessel beams [1,2]. Those of high order are accompanied of a phase factor of the form exp(imφ) that represents a vortex structure with topological charge m. It happens that it is possible to obtain other PIOFs from the Helmholtz equation which also contain vortex structure.
