非线性与啁啾对艾里脉冲传输性质影响的研究
|
Abstract:
本文运用分步傅里叶法对初始啁啾与色散系数符号相同的情况进行数值模拟与分析，结果表明，啁啾的增大将进一步影响脉冲的展宽，影响脉冲传输质量。进一步研究了在自相位调制效应下，非线性系数对脉冲传输变化的影响，结果表明，在一定初始啁啾下，脉冲频谱主瓣强度有明显增大的趋势。
In this paper, the Fractional Fourier method is used to simulate and analyze the case where the initial chirp and the symbol of the dispersion coefficient are the same. The results show that the increase in chirp will further affect the pulse broadening and the pulse transmission quality. The effect of the nonlinear coefficient on pulse transmission is further studied under the self-phase modulation effect. The results show that the intensity of the main lobe of the pulse spectrum tends to increase obviously under a certain initial chirp.
