Pulse train generation in a distributed gain fibre amplifier

Abstract

This work shows the generation of an array of chirped compressed periodic waves with distributed gain in a nonlinear fibre. In particular, with suitable tailoring of the gain to vary along the longitudinal distance while the dispersion and nonlinearity parameters are kept constant. Exact analytical equations using the self-similar analysis technique were obtained to describe this process. In addition, the stability of these generated periodic waves is studied under finite perturbations.
