论文摘要
纤维bragg光栅已被有利地用于改善半导体激光器的混沌性能。尽管已知这些组件对环境条件高度敏感，但反馈阶段的波动通常被忽略。在这项工作中，我们从实验上证明，通过简单的FBG热调节引起的传播时间的较小变化足以诱导激光行为的显着变化。我们报告了与相位变化相关的周期性稳定性增强，并强调了相位变化和相位偏移起着重要作用。最后，我们与基于Lang-Kobayashi模型的扩展版本的模拟显示了一个良好的定性协议。
Fiber Bragg Gratings have been advantageously used to improve the chaotic properties of semiconductor lasers. Though these components are known to be highly sensitive to environmental conditions, feedback phase fluctuations are often neglected. In this work, we experimentally demonstrate that the small variations of the propagation time induced by a simple thermal tuning of the FBG is sufficient to induce significant changes of the laser behavior. We report periodic stability enhancements linked with phase variations and highlight that both phase variation and phase offsets play an important role. Last, we show a good qualitative agreement with simulations based on an expanded version of the Lang-Kobayashi model.
