研究了半导体激光器在相干延迟滤波光反馈作用下的动力学行为。系统的分岔分析表明，该系统支持两种根本不同类型的振荡，即弛豫振荡和外部往返振荡。两者都稳定地发生在大的域的反馈条件下的变化，其中的反馈相位被确定为控制这种动态复杂性的关键量。我们确定了两个独立的参数区域的稳定往返振荡，发生在整个纯频率振荡的形式。
We investigate the dynamics of a semiconductor laser subject to coherent delayed filtered optical feedback. A systematic bifurcation analysis reveals that this system supports two fundamentally different types of oscillations, namely relaxation oscillations and external roundtrip oscillations. Both occur stably in large domains under variation of the feedback conditions, where the feedback phase is identified as a key quantity for controlling this dynamical complexity. We identify two separate parameter regions of stable roundtrip oscillations, which occur throughout in the form of pure frequency oscillations.
