我们报道了一对互锁的克尔-微谐振器频率梳的精确相位稳定。这两个梳子，一个基于氮化硅，另一个基于二氧化硅，具有几乎谐波的重复频率，可以用一个激光器产生。氮化硅梳子支持超快激光体制，具有三光周期、1皮秒周期的孤子脉冲和170太赫兹的总色散波增强带宽，同时在光学和微波频率之间提供稳定的相位链接。我们演示了氮化硅梳子的载波包络偏移频率和光谱轮廓的纳米加工控制。锁相梳子以分数精度相干地重现它们的时钟
We report accurate phase stabilization of an interlocking pair of Kerr-microresonator frequency combs. The two combs, one based on silicon nitride and one on silica, feature nearly harmonic repetition frequencies and can be generated with one laser. The silicon-nitride comb supports an ultrafast-laser regime with three-optical-cycle, 1-picosecond-period soliton pulses and a total dispersive-wave-enhanced bandwidth of 170 THz, while providing a stable phase-link between optical and microwave frequencies. We demonstrate nanofabrication control of the silicon-nitride comb's carrier-envelope offset frequency and spectral profile. The phase-locked combs coherently reproduce their clock with a fractional precision of
