  • Leaky modes in multilayer uniaxial optical waveguides 

    Torner Sabata, Lluís; Canal Bienzobas, Fernando; Hernández Marco, Jordi (1990-04)
    Article
    Open Access
    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 ...
  • 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 Álvarez, 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 ...
  • Imaging amylopectin's order in starch using 3-dimensional polarization SHG 

    Psilodimitrakopoulos, Sotiris; Amat Roldán, Iván; Artigas García, David; Loza Álvarez, Pablo (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2011)
    Conference report
    Restricted access - publisher's policy
    In minimally destructive SHG biomedical imaging (high resolution optical slicing) is greatly desirable to extract the maximum of information from the light matter interaction. Here we develop a 3-D biophysical model and ...
  • Transverse Doppler effect using engineered optical beams 

    Rosales Guzmán, Carmelo; Hermosa, Nathaniel; Belmonte Molina, Aniceto; Pérez Torres, Juan (2013)
    Conference report
    Restricted access - publisher's policy
    When a light beam with a transverse spatially-varying phase is considered for optical remote sensing, in addition to the usual longitudinal Doppler frequency shift of the returned signal induced by the motion of the ...
  • Estudio teórico de una unión Y activa para aplicaciones en dispositivos de óptica integrada 

    Recolons Martos, Jaume; Torner Sabata, Lluís; Canal Bienzobas, Fernando (1988)
    Conference report
    Open Access

  • 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.
  • Reglas de similitud para modos TE en guias opticas no lineales 

    Torres, Josep Lluis; Torner Sabata, Lluís (1991)
    Conference report
    Open Access
    We have shown that the stationary propcrties ofTE guided waves in a slab optical waveguide with a nonlinear Kerr-likc bounding medium can be described in a compact way by means of the usual normalized dfcctive moda.! index ...
