recommendations! Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-20660-z

Abstract: We present a theoretical study and experimental generation of Mathieu–Gauss beams in the partially coherent regime. By means of a rotating ground glass diffuser and a spatial light modulator, we demonstrate independent control over both… read more here.

DOI: 10.1063/5.0013174

Abstract: We investigate light propagation in a two-dimensional aperiodic refractive index lattice realized using the interference of multiple Mathieu–Gauss beams. We demonstrate experimentally and numerically that such a lattice effectively hinders linear light expansion and leads… read more here.

DOI: 10.1073/pnas.2014017117

Abstract: Significance Nanoscale dielectric devices are capable of mediating long-range atom–atom interactions using guided mode photons, as well as long-range photon–photon interactions mediated by lattices of atoms. Such systems have the potential to provide new tools… read more here.

DOI: 10.1103/physreva.102.023533

Abstract: In this work, we establish the relationship existing between astigmatic Gaussian beams and Bessel-modulated Gaussian beams with quadratic radial dependence. We introduce an alternative representation of quadratic Bessel-Gaussian beams. This result permits us to expand… read more here.

DOI: 10.3390/nano13030579

Abstract: This paper presents an efficient method to generate high-order Bessel–Gauss beams carrying orbital angular momentum (OAM) by using a thin and compact optical element such as a multilevel spiral axicon. This approach represents an excellent… read more here.
