一个安静的点，泵浦谐振失谐的工作点，最大限度地减少由于谐振器内部的非线性效应的频率波动，已被采用的相位噪声降低的孤子克尔微谐振器频率梳（微梳）。当然，期望该点的使用还将改善微梳在锁相环中的频率稳定性和忠实性方面的性能。在这项研究中，我们实验研究的影响，在微梳的重复频率为300 GHz。我们在1秒的安静点获得了最低的分数频率不稳定性，为1.5 × 10 − 9，比自由运行的不稳定性低44倍。微梳与稳定的光纤梳的锁相被证明是为了评估反馈回路中的性能，其中微梳和光纤梳之间的6.8 × 10 − 13的环路限制相对分数频率不稳定性被获得作为稳定性限制的指标。
A quiet point, an operating point of pump-resonance detuning that minimizes frequency fluctuation due to nonlinear effects inside a resonator, has been employed for phase noise reduction of a soliton Kerr microresonator frequency comb (microcomb). Naturally, it is expected that the use of the point will also improve performances of a microcomb in terms of frequency stability and faithfulness in a phase locked loop. In this study, we experimentally investigate the effect in a microcomb with a repetition frequency of 300 GHz. We obtain a lowest fractional frequency instability at a quiet point of 1.5 × 10−9 at 1 second, which is 44 times lower than free-running instability. Phase-locking of a microcomb to a stabilized fiber comb is demonstrated to evaluate performance in a feedback loop, where in-loop-limited relative fractional frequency instability between the microcomb and the fiber comb of 6.8 × 10−13 is obtained as an indicator of the stability limitation.
