Optical solitons in birefringent fibers having anti-cubic nonlinearity with extended trial function

Optik, 2019

This paper obtains bright and singular optical solitons that are studied with anti-cubic nonlinearity in birefringent fibers. The extended trial function scheme gave way to these results. The existence criteria of such solitons are also indicated. 1.1. Governing model For polarization preserving fibers, the dynamics of soliton propagation through optical fibers with AC nonlinearity is governed by the nonlinear Schrödinger's equation (NLSE) [1-20]:

Optical solitons in birefringent fibers having anti-cubic nonlinearity with a few prolific integration algorithms

Optik, 2020

This paper obtains bright and singular optical solitons that are studied with anti-cubic nonlinearity in birefringent fibers. The extended trial function scheme gave way to these results. The existence criteria of such solitons are also indicated. 1.1.

Optical solitons in birefringent fibers with spatio-temporal dispersion

Optik, 2014

This paper studies the propagation of solitons through birefringent fibers in the presence of spatiotemporal dispersion. Both Kerr and parabolic laws of nonlinearity are addressed. The exact 1-soliton solutions are obtained. There are several constraint conditions that ensure soliton solutions are derived. Three types of solitons are obtained: bright, dark and singular solitons.

Quiescent Optical Solitons with Cubic–Quartic and Generalized Cubic–Quartic Nonlinearity

Electronics

The enhanced Kudryashov’s approach retrieves quiescent bright, dark, and singular solitons to the governing model that is considered with cubic–quartic form of self-phase modulation. The algorithm however fails to retrieve stationary solitons when the nonlinearity is the generalized version of the cubic–quartic form. The current analysis is conducted with a direct approach without an intermediary phase-portrait analysis as in the past.
