    • Engineering competing nonlinearities 

      Bang, O; Clausen, C B; Christiansen, P L; Torner Sabata, Lluís (1999-10)
      Article
      Accés restringit per política de l'editorial
      Weak modulation of a quasi-phase-matching (QPM) grating opens possibilities for engineering both the average quadratic nonlinearity and the incoherent average cubic nonlinearity induced by QPM. The relative strength of the ...

    • Engineering of effective quadratic and cubic nonlinearities in two-period QPM gratings 

      Bang, O; Clausen, Carl B.; Torner Sabata, Lluís (OPTICAL SOCIETY OF AMERICA, 2000)
      Text en actes de congrés
      Accés obert
      Summary form only given. Quasi-phase-matching (QPM) by electric-field poling in ferro-electric materials, such as LiNbO/sub 3/, is promising due to the possibilities of engineering the photolithographic mask, and thus the ...

    • Engineering of spatial solitons in two-period QPM structures 

      Johansen, S K; Carrasco Rodríguez, Sílvia; Torner Sabata, Lluís; Bang, O (2002-08)
      Article
      Accés restringit per política de l'editorial
      We report on a scheme which might make it practically possible to engineer the effective competing nonlinearities that on average govern the light propagation in quasi-phase-matching (QPM) gratings. Modulation of the QPM ...

    • Robustness of qudratic solitons with periodic gain 

      Torner Sabata, Lluís; Pérez Torres, Juan; Bang, O (2000-11)
      Article
      Accés restringit per política de l'editorial
      We address the robustness of quadratic solitons with periodic non-conservative perturbations. We find the evolution equations for guiding-center solitons under conditions for second-harmonic generation in the presence of ...
