论文摘要
我们分析了光学反馈对在长腔状态下运行的外部腔模式锁定半导体激光器的动力学的影响。根据空腔往返时间与反馈延迟之间的比率,我们通过实验表明反馈充当解决方案鉴别器,可以增强或阻碍多个共存模式锁定的谐波解决方案之一的出现。我们的理论分析很好地再现了实验。由于增益消耗引起的时间对称性破坏,我们确定了不对称的共振舌。
We analyse the effect of optical feedback on the dynamics of external-cavity mode-locked semiconductor lasers operated in the long cavity regime. Depending on the ratio between the cavity round-trip time and the feedback delay, we show experimentally that feedback acts as a solution discriminator that either reinforces or hinders the appearance of one of the multiple coexisting mode-locked harmonic solutions. Our theoretical analysis reproduces well the experiment. We identify asymmetrical resonance tongues due to the temporal symmetry breaking induced by gain depletion.
