Special Issue Information

Dear Colleagues,

Optical soliton generation, manipulation, and applications have received significant attention due to their potential applications in various domains. Optical soliton transmission in several nonlinear waveguides, such as optical fibers, metamaterials, and photonic crystal fiber, have been experimentally and theoretically investigated as a way to explore their dynamical behaviors. In nonlinear theory, various forms of nonlinear Schrödinger equations (NLSs) are used to describe the optical soliton transmission. The dynamical behavior of optical solitons can be investigated by attaining and investigating the soliton solutions of these nonlinear Schrödinger models, which have variable coefficients. The nonautonomous soliton solutions of nonautonomous NLS models are of great importance as their physical characteristics can be modified by changing the control parameters. By controlling system parameters, solitons can potentially be tailored for the design of optical computing devices, ultrafast logic gates, soliton switching devices, path control devices, supercontinuum generation in a fiber, etc. Additionally, to achieve ultrashort pulse propagation, such as that lasting a femtosecond or an attosecond in duration, higher order linear and nonlinear effects must be included in the theoretical models. Modulation instability analysis for inhomogeneous NLS models has also received significant attention because of its remarkable ability to analyze the gain spectrum. Such results are beneficial for applications in fiber lasers and optical-fiber-based photonic integrated devices.

In this context, we welcome research and review articles dealing with nonlinear Schrödinger models, with the aim of providing readers with an improved understanding of nonlinear optical soliton transmission in various nonlinear optical systems.

Topics of interest include, but are not limited to:

  • Nonlinear Schrödinger models;
  • Dynamical properties of optical solitons;
  • Optical soliton control and management;
  • Photonic crystal fiber;
  • Modulation instability in nonlinear waveguides;
  • Supercontinuum generation in nonlinear optical fibers;
  • Applications of optical solitons in photonics.

Abstract
We investigate the interactions of in-phase Airy beams modulated by a fundamental Gaussian beam and fourth-order diffraction in Kerr nonlinear media. Directly numerical simulations show that normal (anomalous) fourth-order diffraction and an in-phase (out-of-phase) Gaussian beam affect the interactions of solitons generated from [...] Read more.
We investigate the interactions of in-phase Airy beams modulated by a fundamental Gaussian beam and fourth-order diffraction in Kerr nonlinear media. Directly numerical simulations show that normal (anomalous) fourth-order diffraction and an in-phase (out-of-phase) Gaussian beam affect the interactions of solitons generated from Airy beams in unique ways. Different from previous results, suggesting that interactions of in-phase (out-of-phase) conventional beams are always attractive (repulsive), many anomalous interactions of Airy beams are obtained. Stable breathing Airy soliton pairs can be formed with fourth-order diffraction and a fundamental Gaussian beam. Full article
