  • Nonlinearity-induced broadening of resonances in dynamically modulated couplers 

    Szameit, Alexander; Kartashov, Yaroslav V.; Heinrich, Matthias; Dreisow, Felix; Keil, R; Nolte, Stefan; Tunnermann, A; Vysloukh, Victor A.; Lederer, F; Torner Sabata, Lluís (2009-01)
    Article

    We report the observation of nonlinearity-induced broadening of resonances in dynamically modulated directional couplers. When the refractive index of the guiding channels in the coupler is harmonically modulated along the ...
  • Observation of two-dimensional coherent surface vector lattice solitons 

    Heinrich, Matthias; Kartashov, Yaroslav V.; Szameit, Alexander; Dreisow, Felix; Keil, R; Nolte, Stefan; Tunnermann, A; Vysloukh, Victor A.; Torner Sabata, Lluís (2009-01)
    Article
    Restricted access - publisher's policy
    We report, to the best of our knowledge, the first experimental observation of vector surface solitons, which form at the edge and in the corner of two-dimensional laser-written waveguide arrays. These elliptically polarized ...
  • Observation of two-dimensional superlattice solitons 

    Heinrich, Matthias; Kartashov, Yaroslav; Ramírez, L. P. R.; Szameit, Alexander; Dreisow, Felix; Keil, R; Nolte, Stefan; Tünnermann, Andreas; Vysloukh, Victor A.; Torner Sabata, Lluís (2009-12)
    Article
    Restricted access - publisher's policy
    We observe experimentally two-dimensional solitons in superlattices comprising alternating deep and shallow waveguides fabricated via the femtosecond-laser direct writing technique. We find that the symmetry of linear ...
  • Two-dimensional solitons at interfaces between binary superlattices and homogeneous lattices 

    Heinrich, Matthias; Kartashov, Yaroslav; Ramírez, L. P. R.; Szameit, Alexander; Dreisow, Felix; Keil, R; Nolte, Stefan; Tünnermann, Andreas; Vysloukh, Victor A.; Torner Sabata, Lluís (2009-12)
    Article

    We report on the experimental observation of two-dimensional surface solitons residing at the interface between a homogeneous square lattice and a superlattice that consists of alternating “deep” and “shallow” waveguides. ...
