Propagation of coupled quartic and dipole multi-solitons in optical fibers medium with higher-order dispersions

Optical Solitons in an Anisotropic Medium with Arbitrary Dipole Moments

We find the Lax pair for a system of reduced Maxwell–Bloch equations that describes the propagation of twocomponent extremely short electromagnetic pulses through the medium containing two-level quantum particles with arbitrary dipole moments.

Perturbation of higher-order solitons by fourth-order dispersion in optical fibers

We study analytically and numerically how the radiation emitted by fundamental solitons in the form of dispersive waves is affected by the third and fourth-order dispersions when a higher-order soliton undergoes the fission process inside an optical fiber. Our results show that two dispersive wave sidebands appear in the output spectrum on opposite sides of the input spectrum. The frequencies o...

Optical Solitons in a Nonlinear Fiber Medium with Higher-Order Effects

Interaction of solitons in tunnel-coupled optical fibers.

A pair of weakly interacting optical fibers, which are described by two nonlinear Schrödinger equations with linear coupling terms, is considered in the framework of perturbation theory. It is shown that the interaction of optical solitons in this system is inelastic and that they may form a bound state (bisoliton). The stability and internal oscillations of the bisoliton are also investigated.

Resonance of solitons in a coupled higher-order Ito equation

In this Letter,we propose a newcoupled higher-order Ito equation andpresent itsN-soliton solutions in Pfaffian form. Furthermore, some interesting examples of soliton resonance related to two solitons near the resonant state are pointed out. © 2012 Elsevier Inc. All rights reserved.
