Abstract
Pulse compression is rarely done in amplifying media with anomalous dispersion (Er/Yb-doped fibres), because it is believed that the resulting pulses will be strongly affected by noise. We have carried out a detailed numerical investigation of the possibility of the higher-order soliton compression at high repetition rate (80 GHz) in such media. The Nonlinear Schrödinger Equation, which includes the Kerr, Raman and self-steepening effects as well as the higher-order dispersion, was solved for a range of initial parameters (input power, nonlinear coefficient, and group velocity dispersion (GVD)). The amplifying medium is preceded by a large-dispersion fibre (A) in which the initial sinusoidal field is shaped to a train of optical solitons. The draft of the according experimental setup in shown in Fig. 1 [1].
