基于Laser的微梳结构中的时间腔孤子：无饱和吸收的自启动脉冲Laser的路径
Temporal Cavity Solitons in a Laser-based Microcomb: A Path to a Self-Starting Pulsed Laser without Saturable Absorption
摘要：
本文从理论上提出了一种基于激光腔孤子的微梳自启动设计，该系统由嵌套在放大激光腔中并与之耦合的微谐振腔组成。我们证明，它是可能的工程系统的零状态的调制不稳定增益，允许启动与一个明确定义的鲁棒孤子的数量。该方法可以通过控制系统参数，如腔长失配和增益形状，来控制产生的孤子的数量和重复率。由于该设置不需要增益饱和，因此结果提供了提供激光锁模的标准技术的替代方案。
英文摘要：
We theoretically present a design of self-starting operation of microcombs based on laser-cavity solitons in a system composed of a micro-resonator nested in and coupled to an amplifying laser cavity. We demonstrate that it is possible to engineer the modulational-instability gain of the system's zero state to allow the start-up with a well-defined number of robust solitons. The approach can be implemented by using the system parameters, such as the cavity length mismatch and the gain shape, to control the number and repetition rate of the generated solitons. Because the setting does not require saturation of the gain, the results offer an alternative to standard techniques that provide laser mode-locking.
