论文摘要
我们通过分析和数值研究来自光纤中单相或双相跳的线性或非线性演变出现的时间强度模式。结果是用直边，条和缝隙的众所周知的衍射模式的干扰来解释的，并且根据纯粹的分散进化而提供了完整的分析框架。当Kerr非线性影响传播时，各种相干的非线性结构会根据分散状态出现。
We analytically and numerically study the temporal intensity pattern emerging from the linear or nonlinear evolutions of a single or double phase jump in an optical fiber. The results are interpreted in terms of interferences of the well-known diffractive patterns of a straight edge, strip and slit and a complete analytical framework is provided in terms of Fresnel integrals for the case of purely dispersive evolution. When Kerr nonlinearity affects the propagation, various coherent nonlinear structures emerge according to the regime of dispersion.
