Perfect vortex beams (PVBs) have intensity distributions independent of their topological
charges. We propose an alternative formulation to generate PVBs through Laguerre–Gauss …

The self-healing phenomenon of structured light beams has been comprehensively
investigated for its important role in various applications including optical tweezing …

Structured light arrays of various shapes have been a cornerstone in optical science, driven
by the complexities of precise and adaptable generation. This study introduces an approach …

In this paper we revisit the nondiffracting properties of the cosine beam (CB). Since the CB is
of infinite extension and not physically realizable, we use two apodization pupils to manage …

To the best of our knowledge, at the present time there is no answer to the fundamental
question stated in the title that provides a complete and satisfactory physical description of …

The generation of structured light from Computer-Generated Hologram (CGH) using spatial
light modulators (SLM) has a wide range of applications, but there is currently a lack of …

In the description of physical systems it is common to discard singular solutions to second
order differential equations due to their apparent lack of physical meaning. Nevertheless, it …

In this paper, we propose a predictor or indicator of the self-healing ability of coherent
structured light beams: the field's modal content. Specifically, the fidelity between the …

Using the asymptotic formula of the Hermite polynomials for higher-orders n≫ 1, an elegant
mathematical expression that makes Hermite–Gaussian beams and cosine beams …

We investigate the capacity of the exact non-Rayleigh nondiffracting (ENRND) speckle field
to reconstruct its statistical properties along the propagation. It is unclear in the literature how …
