Methods for discrete solitons in nonlinear lattices.

چکیده
A method to find discrete solitons in nonlinear lattices is introduced. Using nonlinear optical waveguide arrays as a prototype application, both stationary and traveling-wave solitons are investigated. In the limit of small wave velocity, a fully discrete perturbative analysis yields formulas for the mode shapes and velocity.

Surface solitons in two-dimensional quadratic photonic lattices
Two-dimensional surface solitons have been recently predicted to exist as novel types of discrete solitons localized in the corners or at the edges of two-dimensional photonic lattices. These theoretical predictions were followed by the experimental observation of twodimensional surface solitons in optically-induced photonic lattices and waveguide arrays laser-written in fused silica. Important...
متن کاملDiscrete solitons in photorefractive optically induced photonic lattices.
We demonstrate that optical discrete solitons are possible in appropriately oriented biased photorefractive crystals. This can be accomplished in optically induced periodic waveguide lattices that are created via plane-wave interference. Our method paves the way towards the observation of entirely new families of discrete solitons. These include, for example, discrete solitons in two-dimensiona...
متن کاملOptically-induced reconfigurable photonic lattices for linear and nonlinear control of light
Linear and nonlinear periodic systems are abundant in nature. In optics, a typical example is a closelyspaced waveguide array, in which collective behavior of wave propagation exhibits many intriguing phenomena that have no counterpart in homogeneous media. Even in a linear waveguide array, the diffraction property of a light beam changes due to evanescent Correspondence/Reprint request: Dr. Zh...
متن کاملDiscrete surface solitons in two-dimensional anisotropic photonic lattices
We study nonlinear surface modes in two-dimensional anisotropic periodic photonic lattices and demonstrate that, in a sharp contrast to onedimensional discrete surface solitons, the mode threshold power is lower at the surface, and two-dimensional discrete solitons can be generated easier near the lattice corners and edges. We analyze the crossover between effectively oneand two-dimensional reg...
متن کاملMobility of Discrete Solitons in Quadratic Nonlinear Media
We study the mobility of solitons in lattices with χ (2) (second-harmonic-generating) nonlinearity. Contrary to what is known for their χ (3) counterparts, we demonstrate that discrete quadratic solitons can be mobile not only in the one-dimensional (1D) setting, but also in two dimensions (2D), in any direction. We identify parametric regions where an initial kick applied to a soliton leads to...
