  • Characterization of dielectric spheres by spiral imaging 

    Petrov, Dimitri; Rahuel, Nicolás; Molina Terriza, Gabriel; Torner Sabata, Lluís (2012)
    Article
    Open Access
    We study the spiral spectra scattered off transparent dielectric spheres when probed by different Laguerre–Gaussian light beams, carrying nested topological wavefront dislocations. We show that such scattering data may ...
  • Observation of optical vortex streets in walking-second harmonic generation 

    Molina Terriza, Gabriel; Petrov, Dimitri; Recolons Martos, Jaume; Torner Sabata, Lluís (OPTICAL SOC AMER - (OSA), 2002-04-30)
    Article
    Open Access
  • Observation of the dynamical inversion of the topological charge of an optical vortex 

    Molina Terriza, Gabriel; Recolons Martos, Jaume; Pérez Torres, Juan; Torner Sabata, Lluís; Wright, Ewan M. (AMERICAN PHYSICAL SOC, 2001-07-31)
    Article
    Open Access
  • Properties of the spatial Wigner function of entangled photon pairs 

    González, Noelia; Molina Terriza, Gabriel; Pérez Torres, Juan (2009-10)
    Article
    Open Access
    In this paper we analyze some important characteristics of the spatial Wigner function of entangled photon pairs. We show that the Wigner description of quantum states that live in the infinite-dimensional spacemomentum degree ...
  • The curious arithmetic of optical vortices 

    Molina Terriza, Gabriel; Recolons Martos, Jaume; Torner Sabata, Lluís (Optical Society of America, 2000-08-15)
    Article
    Open Access
    The superposition of noncoaxial light beams containing screw wave-front dislocations is shown to create light patterns with a richer vortex content than that given by the arithmetic of the topological charges of the ...
