Effect of Coherence Relaxation on the Propagation of Optical Solitons: An Analytical and Numerical Case Study on Asymptotic Perturbation Theory

摘要

The propagation of real Raman solitons is studied in the presence of collisional coherence decay by using Kaup's formulation on asymptotic perturbation theory and the symmetry properties of the related sine Gordon equation. Neglecting the continuous spectrum the soliton parameters are calculated both to first order and to all orders in the coupling constant. Numerical results confirm the validity of the latter results.
