Discrete Nonlinear Wave Propagation In Kerr Nonlinear Media
Discrete optical systems are a subgroup of periodic structures in which the evolution of a continuous electromagnetic field can be described by a discrete model. In this model, the total field is the sum of localized, discrete modes. Weakly coupled arrays of single mode channel waveguides have been …

Stable Spatial Solitons In Semiconductor Optical Amplifiers
… of light or a self induced waveguide. Spatial solitons appear as a result of the balance of diffraction and nonlinear focusing in a system. They have been observed in many different conservative media in the last couple of years. Solitons are ubiquitous, because of the probability of using …

Discrete Wave Propagation In Quadratically Nonlinear Media
Discrete models are used in describing various microscopic phenomena in many branches of science, ranging from biology through chemistry to physics. Arrays of evanescently coupled, equally spaced, identical waveguides are prime examples of optical structures in which discrete dynamics can be easily …

Nonlinear waves in systems with PT/CP - symmetric potentials
… nonlinear lattice dynamical models is the discrete nonlinear Schrödinger (DNLS) equation [1]. Particularly, the discrete system and lattice solitons are the main objects of investigation in this work. In this thesis, we consider a chain of dimers, that is modelled by linearly coupled DNLS …

Optical Wave Propagation In Discrete Waveguide Arrays
… arrays is characteristic of that encountered in discrete systems. As a result, it is possible to engineer the diffraction properties of such structures, which leads to the ability to control the flow of light in ways that are impossible in continuous media. In this work, a detailed theoretical …

Classical and quantum nonlinear optics in confined photonic structures
… 13.8 mW, the output spectra consist of multiple discrete solitons that shift continuously to lower energies as they propagate in the lowest transverse mode of the fibre. The number of solitons and the amount that they shift both increase with the launched power. All of the data is quantitatively …
