Light propagating in linear and nonlinear waveguide lattices exhibits behaviour
characteristic of that encountered in discrete systems. The diffraction properties of these …

Nonlinear periodic lattices occur in a large variety of systems, such as biological molecules,
nonlinear optical waveguides, solid-state systems and Bose–Einstein condensates. The …

We review both theoretical and experimental advances in the recently emerged field of
modulated photonic lattices. These artificial periodic dielectric structures provide a powerful …

An AlGaAs waveguide array below the half-bandgap is used to investigate experimentally
basic dynamic features of discrete systems. In particular, nonlinear locking of a discrete …

We present a progress overview focused on the recent theoretical and experimental
advances in the area of soliton manipulation in optical lattices. Optical lattices offer the …

We report the observation of discrete spatial optical solitons in an array of 41 waveguides.
Light was coupled to the central waveguide. At low power, the propagating field spreads as …

We provide an overview of recent experimental and theoretical developments in the area of
optical discrete solitons. By nature, discrete solitons represent self-trapped wavepackets in …

The coherence of waves in periodic systems (lattices) is crucial to their dynamics, as
interference effects, such as Bragg reflections, largely determine their propagation. Whereas …

We investigate the generation of discrete spatial solitons in arrays of coupled waveguides.
Light was launched into the center of the array, and different beam sizes and array …

It is shown that discrete solitons can be navigated in two-dimensional networks of nonlinear
waveguide arrays. This can be accomplished via vector interactions between two classes of …
