We study the dynamics of two vertical-cavity surface-emitting lasers (VCSELs) mutually coupled such that the natural lasing polarization of each laser is rotated by 90 degrees and then is injected into the other laser. Simulations based on the spin-flip model show transient square-wave polarization switchings before a stationary state is reached. The influence of various model parameters on the duration of the stochastic transient time and on the lasers' dynamics in the stationary state is investigated.
我们研究了两个相互耦合的垂直腔面发射激光器（VCSEL）的动力学特性，使得每个激光器的自然激射偏振旋转90度，然后注入到另一个激光器中。基于自旋翻转模型的模拟显示，在达到稳态之前会出现瞬态方波偏振切换。研究了各种模型参数对随机瞬态时间持续时间以及稳态下激光器动力学的影响。
