We demonstrate numerically and experimentally how the presence of so-called Topo-logical Defects represented by junctions within otherwise periodical planar photonic lattices influences the formation of discrete solitons similar to conventional defects constituted by detuned waveguides.
We report on soliton formation in laserwritten two-dimensional binary waveguide lattices. Even for small index contrasts between the sublattices, soliton intensity profiles and power thresholds strongly depend on whether “deep” or “shallow” channels are excited.
We report on the experimental realization of zigzag waveguide lattices, where second-order coupling influences linear and nonlinear light evolution. Band structure deformation and changes in soliton thresholds are analyzed depending on higher-order coupling.
We present a comprehensive experimental analysis of the switching and routing behaviour of light in two-dimensional evanescently coupled waveguide arrays. Exploring the unique properties of such systems, we propose different networking schemes for sophisticated logical operations.
The experimental observation of optical surface vector solitons, which form at the edge and in the corner of two-dimensional laser-written waveguide arrays is reported in this paper. An optically polarized vector states are composed of two coherently interacting orthogonally polarized components. They exist only above a certain power threshold and bifurcate from scalar surface solitons towards higher...
This paper presents the first experimental evidence of switching a linear signal pulse by a blocker-DS in two-dimensional waveguide arrays. Femtosecond-laser waveguide writing technique is employed to fabricate Y- and T-junctions of waveguide arrays in fused silica.
