论文摘要
旨在以多种和可控模式或多波长激光器发射的激光有可能成为未来微波光子技术的关键构件。尽管已经提出了许多依赖光学注射的有趣方案，但多波长激光器的不同模式之间的非线性模式耦合及其在光学注射下的动力学行为仍然充满了大量探索。在这里，我们在实验和数值上研究围绕Dual12波长激光抑制模式的光学注射的影响以及与显性模式的所得相互作用。我们突出显示了由抑制模式的注入锁定触发的主导模式的波长偏移，并报告了模式抑制比对锁定范围的强烈影响。最后，我们从数值上表明，两种模式之间的交叉耦合参数可能在此效果中具有关键作用。
Lasers designed to emit at multiple and controllable modes, or multi-wavelength lasers, have the potential to become key building blocks for future microwave photonic technologies. While many interesting schemes relying on optical injection have been proposed, the nonlinear mode coupling between different modes of a multi-wavelength laser and their dynamical behavior under optical injection remains vastly unexplored. Here, we experimentally and numerically study the effect of optical injection around the suppressed mode of a dual12 wavelength laser and the resulting interactions with the dominant mode. We highlight a wavelength shift of the dominant mode triggered by injection locking of the suppressed mode and report a strong impact of the mode suppression ratio on the locking range. Finally, we show numerically that the cross-coupling parameter between the two modes might have a key role in this effect.
