High-power pulse trains excited by modulated continuous waves
Pulse trains growing from modulated continuous waves (CWs) are considered,
using solutions of the Hirota equation for solitons on a finite background. The
results demonstrate that pulses extracted from the maximally compressed trains
can propagate preserving their shape and forming robust arrays. The dynamics of
double high-power pulse trains produced by modulated CWs in a model of optical
fibers, including the Raman effect and other higher-order terms, is considered
in detail too. It is demonstrated that the double trains propagate in a robust
form, with frequencies shifted by the Raman effect.Comment: 7 pages, 7 figure
