Tolerance of Scalar and Vector Solitons to Random Variations of Map Parameters in Dispersion Managed Optical Fiber Links
Аннотация
The propagation of scalar and vector solitons in dispersion managed optical fiber links with randomly varying map parameters has been studied. Two types of randomness are considered for scalar solitons: random dispersion magnitudes and random lengths of fiber spans. In the case of vector solitons the consequence of the random fiber birefringence has been examined. Disintegration of a scalar soliton and splitting of a vector soliton propagating in such optical communication line are shown to occur by numerical simulations. Comparison between results of numerical simulations, based on the full NLSE and corresponding variational equations reveals their good agreement. Theoretical prediction for the scalar soliton break-up distance in the averaged dynamics limit has been confirmed by numerical solution of corresponding stochastic ODE’s.
