      Artigas García, David; Torner Sabata, Lluís (2005-01)
      Article
      Accés restringit per política de l'editorial
      We show that suitable photonic metamaterial structures can support lossless surface waves of the form envisaged by Dyakonov. The idea we put forward is based on the birefringent properties of photonic crystals in the ...

      Article
      Accés obert
      A new kind of resonator based on a nonlinear directional coupler with feedback is presented. The steady states are found and the map of the system is iterated, showing the existence of bistability, period doubling and ...
    • Dynamics of quadratic soliton excitation 

      Artigas García, David; Torner Sabata, Lluís; Akhmediev, N (1999-04)
      Article
      Accés restringit per política de l'editorial
      We study the dynamics of the soliton–radiation interaction in the process of soliton excitation in quadratic nonlinear media. The focus is on the dynamics of initial signals that are not weakly perturbed exact solitons. ...
    • Effect of molecular organization on the image histograms of polarization SHG microscopy 

      Psilodimitrakopoulos, Sotiris; Amat Roldán, Iván; Loza Álvarez, Pablo; Artigas García, David (2012)
      Article
      Accés obert
      Based on its polarization dependency, second harmonic generation (PSHG) microscopy has been proven capable to structurally characterize molecular architectures in different biological samples. By exploiting this polarization ...
    • Efficiency of quadratic soliton generation 

      López Lago, Elena; Simos, Christos; Couderc, Vincent; Barthélémy, Alain; Artigas García, David; Torner Sabata, Lluís (2001-08)
      Article
      Accés restringit per política de l'editorial
      We report what is believed to be the first experimental demonstration of soliton content as a function of the intensity of input light for multicolor quadratic solitons. Experiments were conducted with spatial solitons ...
    • Enhanced localization of Dyakonov-like surface waves in left-handed materials

      Article
      Accés restringit per política de l'editorial
      We address the existence and properties of hybrid surface waves forming at interfaces between left-handed materials and dielectric birefringent media. The existence conditions of such waves are found to be highly relaxed ...
