We study the influence of delayed optical feedback from a short external cavity on the emission dynamics of semiconductor lasers using the Lang and Kobayashi rate equation model. A combination of numerical integration and continuation techniques allows us to bring new light into the bifurcation scenario leading to the regular pulse packages (RPP) regime. We give examples of bistability between RPP and time-periodic or steady state solutions. Our bifurcation study of RPP regime is complemented by an analysis of the dependency of the RPP period on the laser and feedback parameters. We qualitatively study this new dynamical regime by plotting a two-dimensional map in the feedback parameters space. The occurrence of RPP is furthermore associated with a topological change in the bifurcation diagram and accompanied by the creation of a new type of bifurcation bridge between a mode and an antimode.
我们使用朗和小林速率方程模型，研究了来自短外腔的延迟光反馈对半导体激光器发射动力学的影响。数值积分和延拓技术的结合使我们能够对导致规则脉冲包（RPP） regime的分岔情况有新的认识。我们给出了RPP与时间周期或稳态解之间双稳性的例子。我们对RPP regime的分岔研究通过分析RPP周期对激光器和反馈参数的依赖性得到补充。我们通过在反馈参数空间中绘制二维图，定性地研究了这种新的动力学 regime。此外，RPP的出现与分岔图中的拓扑变化有关，并伴随着在一个模式和一个反模式之间创建一种新型的分岔桥。
