    • Angular surface slitons in sectorial hexagonal arrays 

      Szameit, Alexander; Kartashov, Yaroslav V.; Vysloukh, Victor A.; Heinrich, Matthias; Dreisow, Felix; Pertsch, T; Nolte, Stefan; Tünnermann, A; Lederer, F; Torner Sabata, Lluís (2008-07)

      We report on the experimental observation of corner surface solitons localized at the edges joining planar interfaces of hexagonal waveguide array with uniform nonlinear medium. The face angle between these interfaces has ...
    • Observation of surface solitons in chirped waveguide arrays 

      Szameit, Alexander; Kartashov, Yaroslav V.; Dreisow, Felix; Heinrich, Matthias; Pertsch, T; Nolte, Stefan; Tünnermann, A; Vysloukh, Victor A.; Torner Sabata, Lluís (2008-05)

      We report the observation of surface solitons in chirped semi-infinite waveguide arrays whose waveguides exhibit exponentially decreasing refractive indices. We show that the power threshold for surface wave formation ...
    • Surface solitons at interfaces of arrays with spatially modulated nonlinearity 

      Kartashov, Yaroslav V.; Vysloukh, Victor A.; Szameit, Alexander; Dreisow, Felix; Heinrich, Matthias; Nolte, Stefan; Tünnermann, A; Pertsch, T; Torner Sabata, Lluís (2008-05)

      We address the properties of two-dimensional surface solitons supported by the interface of a waveguide array whose nonlinearity is periodically modulated. When the nonlinearity strength reaches its minima at the points ...
