TL;DR: It is demonstrated that optical discrete solitons are possible in appropriately oriented biased photorefractive crystals in optically induced periodic waveguide lattices that are created via plane-wave interference and paves the way towards the observation of entirely new families of discretesolitons.

TL;DR: The first experimental observation of discrete solitons in an array of optically induced waveguides is reported, paving the way for reconfigurable focusing and defocusing photonic lattices where low-power (mW) discretesolitons can be thoroughly investigated.

TL;DR: In this paper, spatiotemporal discrete solitons are shown to propagate undistorted along a series of coupled resonators or defects by balancing of the effects of discrete lattice dispersion with material nonlinearity.

TL;DR: It is shown that the discrete diffraction properties of a nonlinear optical zigzag waveguide array can be significantly modified, by exploiting the topological arrangement of the lattice itself, to generate altogether different families of discrete soliton solutions, which are stable over a wide range of parameters.

TL;DR: The performance of switching junctions in two-dimensional discrete-soliton networks is analyzed theoretically by coupled-mode theory and can be used for the design of routing junctions with specified operational characteristics.
