Pulse compression dynamics in a nonlinear longitudinally inhomogeneous optical fiber

The output characteristics of a Gaussian frequency-modulated pulse in a longitudinally inhomogeneous single-mode active nonlinear optical fiber are investigated. On the basis of the numerical analysis of the obtained dynamic equations, it is shown that, by means of varying the input pulse parameters and the type of the longitudinal inhomogeneity of the group-velocity dispersion, it is possible to effectively control not only the length and degree of the compression of the propagating pulse but also the number of maximum-compression points along the length of the optical fiber.
