光注入半导体激光器双脉冲激励的一种途径
A Route to Robust Double Pulse Excitability in Optically Injected Semiconductor Lasers
摘要：
提出并分析了光注入量子点半导体激光器的三维模型。这个模型描述了最近的实验单，双可激发强度脉冲，这是有关的中心鞍结同宿分岔的阿德勒方程。双脉冲与倍周期分叉有关，并与单脉冲发生在同一同宿线上。详细描述了巩固单和双可激发脉冲的分叉情况。
英文摘要：
We present and analyse a three-dimensional model for a quantum dot semiconductor laser with optical injection. This model describes recent experimental single and double excitable intensity pulses, which are related to a central saddle-node homoclinic bifurcation as in the Adler equation. Double pulses are related to a period doubling bifurcation and occur on the same homoclinic curve as single pulses. The bifurcation scenario consolidating single and double excitable pulses is described in detail.
