    • 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)
      Article

      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 ...

    • Negative Goos-Hanchen shift in periodic media 

      Rechtsman, Mikael C.; Kartashov, Yaroslav; Setzpfandt, Frank; Trompeter, Henrik; Torner Sabata, Lluís; Pertsch, T.; Peschel, Ulf; Szameit, A. (2011-11-15)
      Article

      We show that, under certain conditions, a negative Goos–Hänchen shift—a longitudinal displacement of a totally internally reflected wave packet—occurs in periodic media such as waveguide arrays.

    • Three-dimensional light bullets in arrays of waveguides 

      Minardi, Stefano; Eilenberger, F.; Kartashov, Yaroslav V.; Szameit, Alexander; Röpke, U.; Kobelke, J.; Schuster, K.; Bartelt, H.; Nolte, Stefan; Torner Sabata, Lluís; LEDERER, FALK; Tünnermann, A.; Pertsch, T. (2010-12-20)
      Article
      Restricted access - publisher's policy
      We report the first experimental observation of three-dimensional light bullets, excited by femtosecond pulses in a system featuring quasi-instantaneous cubic nonlinearity and a periodic, transversally modulated refractive ...
