    • Atmospheric-turbulence-induced power-fade statistics for a multiaperture optical receiver 

      Belmonte Molina, Aniceto; Comerón Tejero, Adolfo; Rubio, Juan Antonio; Fernández (OPTICAL SOC AMER, 1997-01-31)
      Article
      Accés obert
      To estimate the probability distributions of power fades, we consider two basic types of disturbance in electromagnetic wave propagation through atmospheric turbulence: wave-front intensity fluctuations and wave-front ...

    • Guided-to-leaky mode transition in uniaxial optical slab waveguides 

      Torner Sabata, Lluís; Recolons Martos, Jaume; Pérez Torres, Juan (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1993-10-01)
      Article
      Accés obert
      The guided-to-leaky hybrid mode transition in slab optical waveguides made on uniaxial crystals such as LiNbO3, or LiTaO 3, is analyzed. Two different guided-to-leaky transitions have been identified, namely the ordinary ...

    • Inter-islands optical link tests 

      Comerón Tejero, Adolfo; Bará Temes, Francisco Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1990-05-01)
      Article
      Accés obert
      Free-space optical communication systems between satellites and also between a satellite and a ground station foreseen in Europe in the mid-1990's require far-field on-ground experimentation prior to launch. To identify ...

    • Leaky modes in multilayer uniaxial optical waveguides 

      Torner Sabata, Lluís; Hernández Marco, Jordi; Canal Bienzobas, Fernando (OPTICAL SOC AMER, 1990-04-01)
      Article
      Accés obert
      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 ...
