Continuous-wave laser-driven, high-Q Kerr–nonlinear optical microresonators have enabled the generation of optical frequency combs, ultralow-noise microwaves and ultrashort optical pulses at tens of gigahertz repetition rate. Here, we break with the paradigm of the continuous-wave driving and instead use periodic, picosecond optical pulses. In a fibre-based Fabry–Pérot microresonator we observe the deterministic generation of stable femtosecond dissipative cavity solitons ‘on top’ of the resonantly enhanced driving pulses. The solitons lock to the driving pulse, which enables direct all-optical control of the soliton's repetition rate and tuning of its carrier-envelope offset frequency. When compared with continuous-wave-driven microresonators or non-resonant pulsed supercontinuum generation, this new approach is more efficient and can yield broadband frequency combs at an average driving power significantly below the continuous-wave parametric threshold. Bridging the fields of continuous-wave-driven resonant and pulse-driven non-resonant nonlinear optics, these results enable efficient microresonator frequency combs, resonant supercontinuum generation and microphotonic pulse compression.

连续波激光驱动的高Q值克尔（Kerr）非线性光学微谐振器已经能够以数十吉赫的重复频率生成光频率梳，超低噪声微波和超短光脉冲。在这里，我们打破了连续波驱动的范式，而是使用了周期性的皮秒光脉冲。在基于光纤的Fabry-Pérot微谐振器中，我们观察到确定性生成的“飞秒”耗散型腔孤子在谐振增强的驱动脉冲“上方”产生。孤子锁定在驱动脉冲上，从而可以直接对孤子的重复率进行全光学控制，并对其载流子包络偏移频率进行调谐。与连续波驱动的微谐振器或非谐振脉冲超连续谱相比，这种新方法效率更高，并且能够以明显低于连续波参数阈值的平均驱动功率产生宽带频率梳。桥接连续波驱动的谐振和脉冲驱动的非谐振非线性光学领域，这些结果使高效的微谐振器频率梳，谐振超连续谱产生和微光子脉冲压缩成为可能。
