    • Evolution dynamics of discrete-continuous light bullets 

      Eilenberger, F.; Minardi, Stefano; Szameit, Alexander; Roepke, Ulrich; Kobelke, J.; Schuster, K.; Bartelt, H.; Nolte, Stefan; Torner Sabata, Lluís; LEDERER, FALK; Tünnermann, Andreas; Pertsch, T. (2011-07-29)

      We experimentally and numerically investigate the propagation of light bullets (LBs) excited in two-dimensional fiber arrays. The combination of nonlinear self-frequency shift, wavelength dependence of thedispersion, and ...

    • 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)

      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
      Restricted access - publisher's policy
      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. ...
