“…On the other hand, propagation-invariant Airy beams, innately yield a tenfold and fourfold increase in FOV compared to the single-photon Gaussian and Bessel beam light sheets, respectively, while maintaining the high resolution [208,209]. It is also found that the self-healing process is fast in the case of a weak turbid medium, a small size beam width, and low initial coherence, as such this can be used to improve the image quality in a ghost imaging system in a turbid medium (figure 14(d)) [184,210].…”

Self-healing, a counterintuitive but significant effect in structured light, that granting a light field the ability to reconstruct itself after a partial obstruction placed in its propagation path. Here, we will give a comprehensive review of the history and development of self-healing effects, especially highlighting its importance in vector vortex beams carrying spin and orbital angular momenta. Moreover, an unified zoology of self-healing, structured light is proposed to unveil a deeper understanding of its physical mechanism and provide a bird's eye view on diverse forms of self-healing effects of different kinds of complex structured light. Finally, we outline the open challenges we are facing, potential opportunities and future trends for both fundamental physics and applications.

“…Additionally, by utilizing the cross phase, the beam can be rotated during propagation, autofocusing can be performed flexibly, the z-coherence can be enhanced, beam polygonal shaping can be executed, and the beam scintillation of the turbulent disturbance can be mitigated [25][26][27][28][29][30][31]. The cross-phase provides the partially coherent beam with the ability to shape distortions that may occur owing to optical diffraction and obstacles, facilitating robust far-field optical imaging [32][33][34]. However, the present research efforts primarily focus on using cross-phase to manipulate electric fields, intensity, optical coherence, etc., and have not yet used it to carry out phase control of the beam itself.…”

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.

Optical self-healing is a repairing phenomenon of a beam in the propagation, as it is perturbed by an opaque object. In this work, we demonstrate experimentally and theoretically that the moiré distributed dual-microlens array enables to generate optical fields with better healing ability to withstand defects than their counterparts of a single microlens array. By utilizing the double parameter scanning method, the self-healing degree of the optical field is significantly affected by both the interval distance and the relative angle of the dual-microlens arrays. The self-healing level is decreased significantly by lengthening the interval between the two microlens array with a small twist angle, while increasing the angle enhances the self-healing degree. Further study manifests the self-healing process with respect to the size and central location of the obstacle. The research results provide a simple and effective method to generate self-healing optical wave fields, which have potential applications including optical communication, assisted imaging technology, and even intense laser physics.
