We study the propagation of discrete solitons on chains of coupled optical waveguides where finite networks of waveguides are inserted at some points. By properly selecting the topology of these networks, it is possible to control the transmission of traveling solitons: we show here that inhomogeneous waveguide networks may be used as filters for soliton propagation. Our results provide a first...

We discuss a novel type of surface soliton-aberrated surface soliton-appearance in a nonlinear one dimensional photonic crystal and a possibility of this surface soliton formation in two dimensional photonic crystal. An aberrated surface soliton possesses a nonlinear distribution of the wavefront. We show that, in one dimensional photonic crystal, the surface soliton is formed at the photonic c...

We show that a weak Airy pulse can be used to manipulate the dynamics of an optical soliton when propagating at a different wavelength. Our results indicate that an Airy wave packet is considerably more effective in controlling the arrival time of a soliton than a corresponding Gaussian pulse. The nature of these interactions is systematically explored as a function of the initial parameters us...

We show how to generate robust self-sustained clusters of soliton bullets-spatiotemporal (optical or matter-wave) solitons. The clusters carry an orbital angular momentum being supported by competing nonlinearities. The "atoms" forming the "molecule" are fully three-dimensional solitons linked via a staircaselike macroscopic phase. Recent progress in generating atomic-molecular coherent mixing ...

We investigate multi-hump spatial solitary waves and multi-soliton patterns generated by an incoherent interaction of two optical beams in a medium with saturable (e.g. photorefractive) nonlinearity. Applying a bifurcation analysis and numerical relaxation technique, we reveal different scenarios of creating the multi-hump solitons and find the families of solitary waves composed of two mutuall...

We investigate a power tunable junction formed by two interacting spatial solitons self-trapped in nematic liquid crystals. By launching a counter-propagating copolarized probe we assess the guided-wave behavior induced by the solitons and demonstrate a novel all-optical switch. Varying soliton power the probe gets trapped into one or two or three guided-waves by the soliton-induced index pertu...

We report the experimental observation of temporal vector soliton propagation and collision in a linearly birefringent optical fiber. To the best of the authors' knowledge, this is both the first demonstration of temporal vector solitons with two mutually incoherent component fields, and of vector soliton collisions in a Kerr nonlinear medium. Collisions are characterized by an intensity redist...

In this paper, a closed form optical soliton solution is obtained for the nonlinear Schrödinger’s equation with fourth order dispersion in a Kerr law media. The solitary wave ansatze is used to carry out the integration of this equation. Finally, a numerical simulation is given for the closed form soliton solution.

We study analytically and numerically soliton communication links made by use of dispersion-decreasing fibers and parametric amplif iers. We show that bit rates greater than 100 Gbits/s (one channel, one polarization) can be achieved with large amplif ier spacings (as high as 120 km). The Raman effect and soliton interactions are compensated through optical phase conjugation, whereas fiber loss...
