    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 ...
  • Enhanced localization of Dyakonov-like surface waves in left-handed materials 

    Crasovan, L C; Takayama, Osamu; Artigas García, David; Johansen, S K; Mihalache, Dumitru; Torner Sabata, Lluís (2006-10)
    Article
    Restricted access - publisher's policy
    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 ...
