Vector spatial and spatiotemporal laser solitons

Nanophotonics
Dissipative optical solitons, i.e. packets of radiation localized not due to the presence of optical inhomogeneities of the scheme or medium, but due to the balance of energy inflow and outflow in a nonlinear medium, deserve special attention for a ...

Generation and stability of discrete gap solitons

, 2003
We analyze stability and generation of discrete gap solitons in weakly coupled optical waveguides. We demonstrate how both stable and unstable solitons can be observed experimentally in the engineered binary waveguide arrays, and also reveal a connection

Analytical and Numerical Soliton Solutions of the Shynaray II‐A Equation Using the G′G,1G$$ \left(\frac{G^{\prime }}{G},\frac{1}{G}\right) $$‐Expansion Method and Regularization‐Based Neural Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Nonlinear differential equations play a fundamental role in modeling complex physical phenomena across solid‐state physics, hydrodynamics, plasma physics, nonlinear optics, and biological systems. This study focuses on the Shynaray II‐A equation, a relatively less‐explored parametric nonlinear partial differential equation that describes ...

Quiescent Optical Solitons for the Perturbed Radhakrishnan–Kundu–Lakshmanan Equation with Nonlinear Chromatic Dispersion

Journal of Applied Science and Engineering
This paper recovers stationary optical solitons for the perturbed Radhakrishnan–Kundu–Lakshmanan equation with nonlinear chromatic dispersion. There are eight approaches that have been implemented to recover these solitons. A full spectrum of solitons is
