DISPERSION-MANAGED SOLITONS WITH AVERAGE NORMAL DISPERSION

摘要

We study the optical pulse dynamics in a transmission system with periodic variation of dispersion, using the variational approach (VA). The dependence of soliton parameters on dispersion map strength is examined. We find that there is a critical map strength above which finite energy solitons can propagate at zero and normal average dispersion. The existence of two branches of soliton solutions in the normal dispersion regime for different levels of the pulse energy is observed.
