Abstract Creating a structured transverse-intensity distribution that undergoes axial rotation during propagation while preserving its overall shape remains a major challenge, as achieving a stable, continuous, and substantial rotation across the entire beam cross-section has thus far proven elusive.

Abstract The Talbot effect has been extensively investigated in one-dimensional and orthogonal two-dimensional periodic structures; however, its manifestation in skew-periodic lattices remains unexplored. Here, we investigate the Talbot effect in skew-periodic structures using Laguerre-Gaussian beams with both zero and non-zero radial indices.

Optical trapping, orchestrated by intensity-gradient forces and radiation pressure, is a powerful technique in physics and nanotechnology that enables precise control and manipulation of microscopic and nanoscale particles with widespread applications in biotechnology, nanoscience, and fundamental physics research.
