论文摘要
我们研究了B类半导体微区激光器的动力学，该激光器与中性微孔谐振器一起用于常见的制造参数。对于谐振器之间的零失调，我们确定了由激光的归一化泵速率和谐振器之间的耦合强度控制的五个动力区域。这些区域显示出具有足够小或大耦合强度参数值的相位锁定的稳定激光。在这些稳定区域之间，至少一个固定点具有吸引力。参数空间相图中从稳定到不稳定的激光区域的过渡是交叉。
We study the dynamics of a class-B semiconductor microring laser coupled to a neutral microring resonator for common fabrication parameters. For zero detuning between the resonators, we identify five dynamical regions controlled by the normalized pump rate of the laser and coupling strength between the resonators. These regions show stable lasing with phase locking for either sufficiently small or large coupling strength parameter values. Multistability and chaos arise in between these stable regions where at least one fixed point is attractive. The transition from stable to unstable lasing regions in the parameter space phase diagram is a crossover.
