  • Self-homodyne detection of the light orbital angular momentum 

    Belmonte Molina, Aniceto; Pérez Torres, Juan (2012-07-15)
    Article
    Restricted access - publisher's policy
    A simple optical system for the self-homodyne detection of the orbital angular momentum (OAM) carried by optical beams is introduced. We propose two different schemes based on the use of optical hybrids, which could detect ...
  • Decoupled illumination detection in light sheet microscopy for fast volumetric imaging 

    OLARTE, Omar Eduardo; Andilla, Jordi; Artigas García, David; Loza Alvarez, Pablo (Optical Society of American (OSA), 2015-08-04)
    Article
    Restricted access - publisher's policy
    Current microscopy demands the visualization of large threedimensional samples with increased sensitivity, higher resolution, and faster speed. Several imaging techniques based on widefield, point-scanning, and light-sheet ...
  • Leaky modes in multilayer anisotropic optical waveguides 

    Torner Sabata, Lluís; Canal Bienzobas, Fernando; Hernández Marco, Jordi (1990)
    Article
    Restricted access - publisher's policy
    The propagation characteristics of the leaky modes in planar anisotropic waveguides with a multilayer structure have been investigated by means of a compact rigorous formalism. The leakage losses and leaky transition angle ...
  • Non reciprocal phase matching in four-layer magnetooptical waveguides 

    Hernández Marco, Jordi; Canal Bienzobas, Fernando; Torner Sabata, Lluís (1987)
    Article
    Open Access
    Non reciprocal single-mode conversion TE0¿TM0 in a four-layer magnetooptical waveguide has been studied as a function of the external applied magnetic field.
  • Applicability of the.Lorentzian peak method to analyze leaky and lossy optical waveguides 

    Torner Sabata, Lluís; Canal Bienzobas, Fernando (1991-06)
    Article
    Open Access
    Several conclusions concerning the applicability of the Lorentzian peak method to compute the complex propagation constant of leaky and lossy waveguide modes are established.
  • Suppression and restoration of disorder-induced light localization mediated by PT-symmetry breaking 

    Kartashov, Yaroslav V.; Hang, Chao; Konotop, Vladimir V; Vysloukh, Victor A.; Huang, Guoxiang; Torner Sabata, Lluís (2016-01-12)
    Article
    Restricted access - publisher's policy
    We uncover that the breaking point of the PT-symmetry in optical waveguide arrays has a dramatic impact on light localization induced by the off-diagonal disorder. Specifically, when the gain/loss control parameter approaches ...
  • Normalized parameters for Y-branch optical waveguides 

    Recolons Martos, Jaume; Torner Sabata, Lluís; Canal Bienzobas, Fernando (1991-05-01)
    Article
    Open Access
    Y-branch optical waveguides are analyzed in terms of normalized parameters by means of the usual modal analysis. With these parameters the number of variables of the problem is reduced, and universal plots for the mode ...
  • Noise-assisted energy transport in electrical oscillator networks with off-diagonal dynamical disorder 

    De León Montiel, J. Roberto; Quiroz Juarez, Mario A.; Quintero Torres, Rafael; Domínguez Juárez, Jorge Luis; Moya Cessa, Hector M.; Pérez Torres, Juan; ARAGÓN HERNÁNDEZ, JOSÉ LUÍS (Macmillan Publishers, 2015-11-27)
    Article
    Open Access
    Noise is generally thought as detrimental for energy transport in coupled oscillator networks. However, it has been shown that for certain coherently evolving systems, the presence of noise can enhance, somehow unexpectedly, ...
  • Diffraction control in P T -symmetric photonic lattices: from beam rectification to dynamic localization 

    Kartashov, Yaroslav V.; Vysloukh, Victor A.; Konotop, Vladimir V; Torner Sabata, Lluís (2016-01-21)
    Article
    Open Access
    We address the propagation of light beams in longitudinally modulated PT-symmetric lattices, built as arrays of couplers with periodically varying separation between their channels, and show a number of possibilities for ...
  • On the use of structured light in nonlinear optics studies of the symmetry group of a crystal 

    Jauregui, Rocio; Pérez Torres, Juan (Macmillan Publishers, 2016-02-08)
    Article
    Open Access
    We put forward a technique that allows to extract information about the symmetry group to which certain nonlinear crystals belong using a single illuminating beam. It provides such information by considering the outcome ...
