High-power pulse trains excited by modulated continuous waves

摘要

Pulse trains growing from modulated continuous waves (CWs) are considered,using solutions of the Hirota equation for solitons on a finite background. Theresults demonstrate that pulses extracted from the maximally compressed trainscan propagate preserving their shape and forming robust arrays. The dynamics ofdouble high-power pulse trains produced by modulated CWs in a model of opticalfibers, including the Raman effect and other higher-order terms, is consideredin detail too. It is demonstrated that the double trains propagate in a robustform, with frequencies shifted by the Raman effect.
