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. 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 as well. It is demonstrated that the double trains propagate in a robust form, with frequencies shifted by the Raman effect. (C) 2015 Optical Society of America
