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.
