چکیده
A dispersion-managed optical system with step-wise periodical variation of dispersion is studied in a strong dispersion map limit in the framework of path-averaged Gabitov-Turitsyn equation. The soliton solution is obtained by iterating the pathaveraged equation analytically and numerically. An efficient numerical algorithm for obtaining of DM soliton shape is developed. The envelope of soliton oscillating tails is found to decay exponentially in time while the oscillations are described by a quadratic law.

متن کاملPERFORMANCE ASSESSMENT OF 10 Gb/s DISPERSION MANAGED SOLITON COMMUNICATION SYSTEMS: AN ANALYTICAL APPROACH
In this paper, we assess the performance of 10 Gb/s dispersion managed soliton communication systems using an analytical approach. The benefits of enhanced power solitons over conventional solitons are carefully evaluated. It is shown that transmission beyond 10 Mm is possible using an appropriate dispersion map, without any additional soliton control technique. An optimum path-average dispersi...
متن کاملDispersion-managed soliton in optical fibers with zero average dispersion.
A dispersion-managed optical system with stepwise periodic variation of dispersion is studied in the framework of a path-averaged Gabitov-Turitsyn equation. The soliton solution is obtained by means of iterating the path-averaged equation. The dependence of soliton parameters on dispersion map strength is investigated, together with the oscillating tails of the soliton.
متن کاملOn the Boundary of the Dispersion - Managed Soliton Existence
Propagation of optical pulse in nonlinear media with varying dispersion is both fundamental [1] and important applied problem [2–8] because the dispersion-managed (DM) system, which is a system with periodic dispersion variation along an optical fiber, is one of the most prospective candidate for ultrafast high-bit-rate optical communication lines. Lossless propagation of optical pulse in DM fi...
متن کاملInstabilities of dispersion-managed solitons in the normal dispersion regime
Dispersion-managed solitons are reviewed within a Gaussian variational approximation and an integral evolution model. In the normal regime of the dispersion map (when the averaged path dispersion is negative), there are two solitons of different pulse duration and energy at a fixed propagation constant. We show that the short soliton with a larger energy is linearly (exponentially) unstable. Th...
