  • Coupling plasmons and dyakonons 

    Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (2012-06-01)
    Article
    Accés restringit per política de l'editorial
    We study the coupling of plasmons and Dyakonov surface waves propagating at the interfaces between isotropic-birefringent-metal layered structures. Efficient coupling is shown to occur with a proper choice of the crystal ...
  • Dyakonov surface wave resonant transmission 

    Takayama, Osamu; Nikitin, A. Yu; Martin-Moreno, Luis; Torner Sabata, Lluís; Artigas García, David (2011-03-28)
    Article

    The role of Dyakonov surface waves in the transmission through structures composed of birefringent media is theoretically explored. In the case of structures using prisms, unexpected high transmission above the critical ...

  • 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
    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 ...
  • Lossless directional guiding of light in dielectric nanosheets using Dyakonov surface waves 

    Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (2014-06-01)
    Article
    Accés restringit per política de l'editorial
    Guiding light at the nanoscale is usually accomplished using surface plasmons(1-12). However, plasmons propagating at the surface of a metal sustain propagation losses. A different type of surface excitation is the Dyakonov ...
  • Nano guiding of light using Dyakonov waves 

    Takayama, Osamu; Torner Sabata, Lluís; Artigas García, David (2014-12)
    Article

    This special issue of Optics & Photonics News highlights the most exciting peer-reviewed optics research to have emerged over the past 12 months.
  • Nano Guiding of Light Using Dyakonov Waves 

    Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (OSA, 2014-12-01)

  • Observation of Dyakonov surface waves 

    Takayama, Osamu; Crasovan, I; Artigas García, David; Torner Sabata, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Summary form only given. A special type of surface wave was predicted by M. I. Dyakonov in 1988. Such waves exist under special conditions at the interface of transparent anisotropic materials, and hens they are lossless. ...
  • Observation of Dyakonov surface waves 

    Takayama, Osamu; Crasovan, L; Artigas García, David; Torner Sabata, Lluís (2009-01)
    Article
    Accés restringit per política de l'editorial
    We report the first experimental observation of Dyakonov surface waves existing at the interface of transparent anisotropic crystals. A Otto-Kretchmann configuration was used to excite the surface waves at the interface ...
  • Practical dyakonons 

    Takayama, Osamu; Artigas García, David; Torner Sabata, Lluís (2012-10-12)
    Article
    Accés restringit per política de l'editorial
    We show that engineered photonic metamaterials composed of alternating layers of suitable dielectrics and metals can support different kinds of surface waves (SWs) under robust and readily achievable experimental conditions. ...
