Bright and dark spatial gap solitons are demonstrated in waveguide arrays. These gap
solitons travel across the array at zero transverse velocity, in complete analogy with …

Nonlinear optical studies of periodic dielectric structures have blossomed in the past two
decades. New fabrication techniques are producing fiber grating and multidimensional …

We analyze nonlinear collective effects in periodic systems with multigap transmission
spectra such as light in waveguide arrays or Bose-Einstein condensates in optical lattices …

Collective effects leading to spatial, temporal or spatiotemporal pattern formation in complex
nonlinear systems driven out of equilibrium cannot be described at the single-particle level …

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

We predict that photonic moiré patterns created by two mutually twisted periodic sublattices
in quadratic nonlinear media allow the formation of parametric solitons under conditions that …

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 …

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

We review the properties of optical spatial dissipative solitons (SDS). These are stable, self‐
localized optical excitations sitting on a uniform, or quasi‐uniform, background in a …

In the course of the past several years, a new level of understanding has been achieved
about conditions for the existence, stability, and generation of spatiotemporal optical …
