Special Issue Information

Dear Colleagues,

The manipulation of the vortex phase in the optical field has given rise to a new subject, namely singularity optics, whose main research object is the vortex beam. Vortex beams possess novel physical properties, such as a spiral wave front, phase singularity and orbital angular momentum, which have important applications in particle manipulation, quantum information, super-resolution imaging, biomedicine, optical communication, nano machining, and astronomical detection, among others. Coherence, as another important inherent property of the light field, is also controllable. The manipulation of the coherence of the light field, especially joint control using the vortex phase, can cause some unique physical effects (such as coherent singularity, beam shaping, self-healing, polarization state conversion, nonlinearity enhancement, anti-turbulence, etc.), and show unique advantages and application prospects in the fields of free-space optical communication, ghost imaging, atmospheric detection, nonlinear optics and information encryption. This Special Issue aims to discuss the latest advances in the coherence manipulation, propagation and application of vortex beams, and the subsequent development of new light field manipulation principles and the proposal of effective solutions to address various challenges in the practical application of vortex light fields.

In this study, we explore the impact of the astigmatism phase on the evolution of the phase singularity of an orbital angular momentum (OAM) beam propagating through free space. The results demonstrate that the high-order phase singularity dispersed into a cluster of individual unit phase singularities owing to the astigmatism phase. The number of singularities equaled the topological charge of the OAM beam. By adjusting the astigmatism phase, we could manipulate and control the evolution of the phase singularities, including their displacements and rotation angles. These findings offer significant prospects for customizing 3D vortex lines, optical topologies, and applications involving topological charge measurement, information encoding, and transfer.

Vortex beams are unique in that they have annular spatial profiles and carry orbital angular momentum. This has led to their use in applications including laser processing, microparticle manipulation and signal transmission. Off-axis vortex beams, which may be considered a subset of vortex beams, display a broader spectrum of physical characteristics in comparison with their conventional (integer-order) counterparts. In this work, we derive the equations which describe the intensity distribution of off-axis vortex beams and use these to theoretically model their spatial profile. These models are supported by experimental generation of both integer and off-axis vortex beams, and the presence of orbital angular momentum is investigated through the use of the cylindrical lens transformation method.

A partially coherent off-axis double vortex beam (PCOADVB) composed of two off-axis vortices is theoretically presented. The analytical equations of a PCOADVB in oceanic turbulence are presented, and the intensity profiles and the number of coherence vortices of the PCOADVBs are investigated based on the derived expressions. The numerical results show that the intensity profiles of PCOADVBs are determined by the initial topological charges M1 and M2 and the positions of the off-axis vortices (x1d,y1d) and (x2d,y2d). The intensity profiles of PCOADVBs will lose the off-axis ring intensity profile and acquire a Gaussian-like profile as z increases, and stronger oceanic turbulence and a smaller σ can help the PCOADVB evolve into a spot with a Gaussian-like profile faster on propagation. The number of coherence vortices of a PCOADVB in oceanic turbulence will increase on propagation. The PCOADVB may have potential applications in underwater laser sensing and wireless communications.
