To date, all of the Laguerre–Gaussian (LG) correlated Schell-model beams proposed and studied are restricted to the standard form with the beam mode indices (0, l), termed as a SLG0lCSM beam. We propose, for the first time, the elegant and standard higher-order LG correlated Schell-model beams as an extension to a SLG0lCSM beam. We develop theoretical formulae to determine the beam mode indices of a vortex beam and describe propagation effects of such beams. We demonstrate that by controlling the beam mode indices, one can produce different intensity distribution patterns during propagation, for example, a dark or solid core surrounded by bright concentric rings. Moreover, using our proposed beams, we illustrate how single-layer and multi-layer adjustable optical cages can be formed near the back of the focal zone of a lens. As anticipated, the proposed beams may find important applications in particle trapping, optical manipulation and optical communications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
