摘要:

利用自注入锁定过程在微谐振器中实现了耗散孤子克尔频率梳。它们具有交钥匙确定性梳产生和简化正常色散区暗孤子产生的优点。在这里,自注入锁定触发的暗脉冲的形成过程进行了研究,把它们看作是一对畴壁连接具有不同的腔内功率的畴。自注入锁定机制允许畴壁自调节它们的位置,使得可以访问宽范围的暗梳状态,并且占空比由反馈相位控制。利用电光采样技术对暗脉冲波形进行直接成像,验证了理论的正确性。研究结果为这类重要的非线性波提供了新的物理见解和新的操作模式。

英文摘要:

Dissipative soliton Kerr frequency combs in microresonators have recently been demonstrated with the self-injection locking process. They have the advantage of turnkey deterministic comb generation and simplifying dark soliton generation in the normal dispersion regime. Here, the formation process of dark pulses triggered by self-injection locking is studied by regarding them as a pair of domain walls that connect domains having different intracavity powers. The self-injection locking mechanism allows the domain walls to self-regulate their position so that a wide range of dark comb states can be accessed, and the duty cycle is controlled by the feedback phase. Direct imaging of the dark pulse shape using the electro-optic sampling technique is used to verify the theory. The results provide new physical insights as well as a new operational modality for this important class of nonlinear waves.
