      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)
