In this paper, we investigate the modulation instability and the dynamics of solitary waves in
a higher-order nonlinear Schrödinger equation. We use a powerful and robust method …

The main goal of the present study is to conduct a deeper investigation into a generalized
Schrödinger equation describing the propagation of optical pulses in media. To this end, the …

This paper focuses on the use of the Sardar sub-equation method to obtain optical solitons
for a nonlinear model that incorporates Kudryashov's quintuple power law and dual-form …

Optical soliton has become one of the most effective transmission carriers in optical
communication system by virtue of its own characteristics and transmission properties. In this …

The multi-soliton collision is an important topic when the distance between solitons is very
small. This work studies the dynamics of solitons in an optical system possessing third-order …

This paper presents an analytical treatment of the perturbed nonlinear Schrödinger equation
(P-NLSE) using the Lie symmetry method. The NLSE is a fundamental equation in nonlinear …

This paper presents optical solitons with the concatenation model having spatio-temporal
and chromatic dispersions. This model can advantageously curtail the Internet bottleneck …

The present paper derives highly dispersive soliton solutions in a coupler from optical
metamaterials with Kerr law of nonlinear refractive index. In nonlinear optics and photonics …

In this paper, we study the characteristics of pure-quartic optical solitons in a nonlinear
medium having a weakly nonlocal response. We propose an nonlinear Schrödinger …

Abstract Objective: The generalized Schrödinger–Hirota equation of the fourth order is
considered using the traveling wave solutions. Method: The compatibility of the …
