      Ibarra Fusté, Jose Antonio; Santos Blanco, M. Concepción (2013-07)
      Article
      Accés restringit per política de l'editorial
      Compact closed-form mathematical expressions for the propagation parameters (characteristic impedance, effective permittivity and attenuation) of coplanar waveguides (CPW) are presented. The formulas take into account ...

    • 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 ...

    • New approaches for the fabrication of photonic structures of nonlinear optical materials 

      Carvajal, J J; Peña, A; Kumar, R.; Pujol, M. C.; Mateos, X.; Aguiló Díaz, Magdalena; Díaz, F; Vázquez De Aldana, J. R.; Méndez, Carlos Alberto; Moreno, P; Roso, L; Todorov Trifonov, Trifon; Rodríguez Martínez, Ángel; Alcubilla González, Ramón; Král, Z; Ferré Borrull, J.; Pallarès Marzal, Josep; Marsal, L F; Finizio, Sergio Di; Martorell Pena, Jordi; Macovez, Roberto (2009-12)
