Observation of surface gap solitons in semi-infinite waveguide arrays
Christian R. Rosberg, Dragomir N. Neshev, Wieslaw Krolikowski +4
We report on the first observation of surface gap solitons, recently predicted to exist at the interface between uniform and periodic dielectric media with defocusing nonlinearity…
Demonstration of all-optical beam steering in modulated photonic lattices
Christian R. Rosberg, Ivan L. Garanovich, Andrey A. Sukhorukov +3
We demonstrate experimentally all-optical beam steering in modulated photonic lattices induced optically by three beam interference in a biased photorefractive crystal. We identify…
Crossover from self-defocusing to discrete trapping in nonlinear waveguide arrays
Michal Matuszewski, Christian R. Rosberg, Dragomir N. Neshev +6
We predict a sharp crossover from nonlinear self-defocusing to discrete self-trapping of a narrow Gaussian beam with the increase of the refractive index contrast in a periodic pho…
Discrete interband mutual focusing in nonlinear photonic lattices
Christian R. Rosberg, Dragomir N. Neshev, Andrey A. Sukhorukov +2
We study nonlinear coupling of mutually incoherent beams associated with different Floquet-Bloch waves in a one-dimensional optically-induced photonic lattice. We demonstrate exper…
Tunable positive and negative refraction in optically-induced photonic lattices
Christian R. Rosberg, Dragomir N. Neshev, Andrey A. Sukhorukov +2
We study tunable refraction of light in one-dimensional periodic lattices induced optically in a photorefractive crystal. We observe experimentally both positive and negative refra…
