Abstract
A variational analysis of dynamics of soliton solution of coupled nonlinear Schrödinger equations with oscillating terms is made, considering a birefringent fiber with a third‐order nonlinearity in the anomalous dispersion frequency region. This theoretical model predicts optical soliton oscillations in lossy fibers.
Highlights
The propagation of bright solitons in birefringent optical fibers has been the subject of intensive theoretical and experimental investigations during the past two decades
Studies of bright soliton propagation in fibers are demanding with reference to the development of soliton-based optical communication, generation of short pulses, and soliton lasers
We follow an adiabatic approach using a variational technique [1] to study dynamics of bright solitons generated from semiconductor lasers in a lossy birefringent fiber
Summary
A variational analysis of dynamics of soliton solution of coupled nonlinear Schrödinger equations with oscillating terms is made, considering a birefringent fiber with a third-order nonlinearity in the anomalous dispersion frequency region. This theoretical model predicts optical soliton oscillations in lossy fibers. 2000 Mathematics Subject Classification: 34A25, 35A15, 35Q55, 37K40, 78A60
