中文摘要: 光学怪波由于其奇异的特征、费解的物理机制以及潜在的应用价值,受到国内外物理学者的广泛关注。到目前为此,光学怪波的研究主要涉及两个方面:一超连续谱产生过程中的光学怪波研究,二基于可积系统下的精确怪波解的研究。前者是在噪声系统中随机产生的统计分布问题;后者是围绕特殊有限背景解展开的具有相似形状的确定性问题。本项目根据光学怪波特征和产生机制,力图在这两个方面研究中去挖掘其实际应用性。具体内容将以广义的非线性薛定谔方程和高阶非线性薛定谔方程为基本模型,通过求解模型的精确和数值怪波解来研究非线性光纤系统中的超连续产生过程中怪波的频谱展宽特征、提取高功率脉冲串、脉冲阶段性放大、相互作用等动力学问题。

英文摘要: Optical rogue wave has been extensively attention due to its fantastic feature, magic physical mechanism and significative application value. Recently,the most researcher focus on two aspects: the research of optical rogue wave in the process of generating supercontinuum and the exact solution of optical rogue wave in different types of NLS equation.The former is the statistical distribution problem of random noise. The latter is the deterministic problem with similar shape based on special limited background soliton solutions. In the project, we consider the general nonlinear Schrödinger equation and the nonlinear Schrödinger equation as theoretical model. By combining analytic solutions and numerical simulations, spectrum broadening of supercontinuum, the method of extracting high power pulses trains, Periodic amplification of optical pulse and interaction of rogue wave in nonlinear optical fiber system will be studied, respectively.
