TL;DR: In this paper, the influence of a sufficiently nonstationary Raman contribution to nonlinear susceptibility on the dynamics of cnoidal wave propagation in optical fibers is theoretically analyzed and the dependence of the parameter that describes the curvature of the propagation trajectory on the degree of localization of the wave energy is presented.

TL;DR: This work puts forward what it believes to be a novel strategy to achieve synthetic nonlinearities where local and nonlocal contributions compete on a similar footing, thus yielding intermediate tunable responses ranging from local to strongly nonlocal.

TL;DR: In this paper, surface solitons supported by the interface of optical lattices imprinted in saturable media with surface-localized gain are considered. But the results show that the presence of a thin amplifying layer near the surface results in controllable emission of soliton towards the lattice at angles depending on the amplification rate and on lattice depth.

TL;DR: In this article, a review of the properties of the families of one-dimensional periodic wave propagating in saturable Kerr-type and quadratic nonlinear media is presented.

TL;DR: This work finds families of thresholdless surface waves existing owing to the combined action of thermally-induced refractive index modulations and instantaneous Kerr-type nonlinearity in semiconductor materials illuminated by modulated light beams.
