We report the results of our study on the in-gap soliton-like solutions in a system of a uniform finite deep nonlinear Bragg grating with a mirror and continuous light source on the opposite sides of the grating. The system was shown to exhibit a new feature consisting of homoclinic and heteroclinic orbits in phase plane associated with the in-gap bright and dark/antidark solitons respectively. The multi-valued connection between the dark and antidark solitons was explicitly displayed. It was further demonstrated that a transition from dark to antidark soliton could be affected by either chang

A study of nonlinear Bragg grating has been carried out using a modified scheme of approximation originally proposed by Iizuka and de Sterke. A complete classification of the solitonic solutions in the system was given. We further demonstrated in this work the existence of in-gap dark and antidark soliton, in addition to the out-gap solutions reported previously. We also found at the boundaries in the bifurcation diagram, the large-amplitude out-gap antidark soliton and broad in-gap dark soliton.

We have demonstrated by Hirota's bilinear method the existence of a new class of bright spatial soliton solutions from the same model of nonlinear optical Bragg grating considered previously by another group of researchers. The explicit expressions obtained from these soliton profiles are distinctly different from the previous results and offer a much more flexible choice of physical parameters for device design. It was further shown that the present formulation provides a classification scheme incorporating previous results as special cases of different parameter sets. Finally, due to the dif

We study dynamics of Bragg grating solitons in a system of linearly coupled Bragg gratings with Kerr nonlinearity. The effects of dispersive reflectivity on the behaviour of solitons in the system are investigated by solving the coupled mode equations numerically. Gap solitons, are found to exist throughout the bandgap of the structure. The system supports two types of symmetric and asymmetric solitons that can have any velocities from zero to the speed of light in the medium. At given soliton parameters a critical coupling coefficient is found above which only symmetric solitons exist. Below

The dynamics of Bragg solitons are investigated in a linearly coupled dual-core fiber, where one core is uniform and has Kerr nonlinearity while the other core is linear and has a Bragg grating with dispersive reflectivity. The system’s dispersion relation gives rise to three disjoint bandgaps; a central gap surrounded by two other gaps — one is located in the upper half and the other is in the lower half of the spectrum. Soliton solutions are only found in the upper and lower gaps. It is found that in certain parameter ranges, solitons develop sidelobes. Exact analytical expressions have been

Coupled-mode equations (CMEs) with self-focusing Kerr and competing quintic nonlinearities were used to investigate solitons in cubic-quintic nonlinear Bragg gratings. Solitons were found throughout the bandgap, with any velocity between 0 and the speed of light. They exist as two disjoint families, known as Type 1 and Type 2. Type 1 solitons are a generalisation of solitons in Kerr media, while quintic nonlinearity is dominant for Type 2 solitons. In Kerr media, slightly over half of the solitons are known to be stable. By numerical propagation, it was found that quintic nonlinearity can sign

Soliton states in three coupled optical waveguide systems were studied: two linearly coupled waveguides with quadratic nonlinearity, two linearly coupled waveguides with cubic nonlinearity and Bragg gratings, and a quadratic nonlinear waveguide with resonant gratings, which enable three-wave interaction. The methods adopted to tackle the problems were both analytical and numerical. The analytical method mainly made use of the variational approximation. Since no exact analytical method is available to find solutions for the waveguide systems under study, the variational approach was proved t

The stability and dynamics of solitons are investigated in a dual-core nonlinear system in which a uniform grating is coupled with a non-uniform grating. Quiescent and moving soliton solutions are attained by performing numerical analysis for various system parameters (e.g., dispersive reflectivity, coupling coefficient, detuning frequency and soliton velocity). The existences of quiescent and moving solitons are analysed by investigating their dispersion relation in laboratory and moving frame, respectively. Sidelobes appear in the soliton tails after a moderate dispersive reflectivity value.

There exist symmetric and asymmetric gap solitons within each family. These gap solitons can have any velocity between zero and the speed of light in the medium.

Bragg grating solitons are investigated in a linearly coupled dual core system, in which one core exhibits Kerr nonlinearity and is equipped with a nonuniform Bragg grating with dispersive reflectivity, while the other core is linear and unperturbed. When relative group velocity in the linear core c is zero, the dispersion relation of the linearized system gives rise to two disjoint gaps in the upper and lower halves of the spectrum. When c ≠ 0, the central gap emerges in the linear spectrum. Soliton solutions do not exist in the central gap but they exist as a continuous family of solutions i

This thesis presents a comprehensive theoretical study of the different characteristics of Bragg solitons in a semilinear dual-core system, where one core consists of cubic-quintic nonlinearity, while the other core is linear and equipped with uniform fibre Bragg gratings. The investigation begins with developing the representative coupled-mode equations, which then leads us to find an analytical solution for the mathematical model when the relative group velocity in the linear core, c, is zero. For non-zero values of c, the solutions must be found by implementing numerical techniques. We cons

Recently we reported the first systematic experiments describing high intensity pulse propagation in fiber Bragg gratings [1-3]. These experiments demonstrated nonlinear pulse compression, and pulse shaping, and also demonstrated the generation and propagation of grating solitons [1]. which exist because of the balancing of nonlinearity of the glass and the strong dispersion of the grating [4-6]. Possibly the most striking feature of these solitons is that they can travel at velocities between zero and the speed of light in the medium.

A balance of group velocity dispersion and nonlinear phase shift in AlGaAs waveguides with buried Bragg gratings is predicted to result in the propagation of gap solitons. Photonic gaps wide enough in wavelength to linearly reflect all Fourier components of the 0.5-ps input pulse being used in the initial experiments require a large modulation depth for the buried grating. Fabrication techniques include electron cyclotron etching and regrowth using MOCVD. The composition of the waveguide is at Al concentrations 0.2 so that the input pulse wavelength of 1.685 μm corresponds to excitation below

The interplay of the Kerr-induced nonlinear refractive index changes and dispersion in nonlinear Fiber Bragg Gratings (FBGs) leads to a plethora of nonlinear phenomena, the most striking of which is perhaps the formation and propagation of gap solitons [1]. Whilst a considerable amount of theoretical work has been performed in this area [1,2,3,4] experimental observations of nonlinear grating behaviour are limited, principally by the difficulty in getting sufficiently high power densities within the core of a FBG in a suitable spectral and temporal range.

A recent experiment on slowly-traveling localized states has been reported by Eggleton et al. in an index-modulated fiber through the Kerr effect [2].
