对光注入可调谐三段半导体激光器的非线性动力学进行了数值研究。第一次，据我们所知，我们提出的稳定性地图，显示不同类型的非线性行为与光学注入参数，调谐曲线的不同点。稳定锁定，极限环，和混沌的区域以周期性的方式变化的激光频率进行阶梯形调谐控制的指数的分布布拉格反射器部分。给出了与弛豫振荡频率和阻尼因子有关的物理解释。这些现象表明，调谐可以是一种有效的方式来控制激光器的稳定性。
Nonlinear dynamics of an optically-injected tunable three-section semiconductor laser have been investigated numerically. For the first time, to the best of our knowledge, we present stability maps, showing different types of the nonlinear behavior versus optical injection parameters, for different points of the tuning curve. Areas of stable locking, limit-cycle, and chaos change in a periodic manner as the lasing frequency undergoes staircase-shaped tuning controlled by the index of the distributed Bragg reflector section. Physical explanation relating this behavior to that of the relaxation oscillation frequency and damping factor is provided. These phenomena suggest that tuning can be an effective way to control laser stability properties.
