Abstract
We present an analysis of long-distance propagation for short optical solitons in a nonlinear optical fiber incorporating the effects of periodic phase conjugation and dispersion management. The analysis includes the Raman self-frequency shift, third-order dispersion, and nonlinear dispersion. The periodic conjugation compensates for the group velocity dispersion, self-phase modulation and Raman self-frequency shift; we show that stable pulse propagation results from the the balance of the (negative) third-order dispersion and the nonlinear dispersion. Judicious choice of the dispersion map negates perturbations due to linear loss; the analysis predicts parameters for the dispersion map that minimize pulse distortion.
