Observation of two-dimensional defect surface solitons
A. Szameit, Y. V. Kartashov, M. Heinrich +7
We report on the experimental observation of two-dimensional solitons located in a defect channel at the surface of a hexagonal waveguide array. The threshold power for the excitat…
Soliton excitation in waveguide arrays with an effective intermediate dimensionality
A. Szameit, Y. V. Kartashov, F. Dreisow +7
We reveal and observe experimentally significant modifications undertaken by discrete solitons in waveguide lattices upon the continuous transformation of the lattice structure fro…
Observation of surface solitons in chirped waveguide arrays
A. Szameit, Yaroslav V. Kartashov, F. Dreisow +6
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…
Surface solitons at interfaces of arrays with spatially-modulated nonlinearity
Y. V. Kartashov, V. A. Vysloukh, A. Szameit +6
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 st…
Diffraction-managed solitons and nonlinear beam diffusion in modulated arrays of optical waveguides
Alexander Szameit, Ivan L. Garanovich, Matthias Heinrich +10
We study propagation of light in nonlinear diffraction-managed photonic lattices created with arrays of periodically-curved coupled optical waveguides which were fabricated using f…
