    Generation of programmable 3D optical vortex structures through devil s vortex-lens arrays 
    Calabuig, Alejandro; Sánchez Ruiz, Sergio; Martínez León, Lluis; Tajahuerce Romera, Enrique; Fernández Alonso, Mercedes; Furlan, Walter Daniel; Monsoriu Serra, Juan Antonio; Pons Martí, Amparo (Optical Society of America, 2013-08-10)
    Different spatial distributions of optical vortices have been generated and characterized by implementing arrays of devil's vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the ...

    Spiral sound-diffusing metasurfaces based on holographic vortices 
    Jimenez, Noe; Groby, Jean-Philippe; Romero-García, Vicent (Nature Publishing Group, 2021-05-13)
    [EN] In this work, we show that scattered acoustic vortices generated by metasurfaces with chiral symmetry present broadband unusual properties in the far-field. These metasurfaces are designed to encode the holographic ...

    Symmetry, winding number, and topological charge of vortex solitons in discrete-symmetry media 
    Garcia March, Miguel Angel; Ferrando Cogollos, Albert; Zacarés González, Mario; Sahu, Sarira; Ceballos Herrera, Daniel Enrique (American Physical Society, 2009-05)
    [EN] We determine the functional behavior near the discrete rotational symmetry axis of discrete vortices of the nonlinear Schrodinger equation. We show that these solutions present a central phase singularity whose charge ...
