摘要:

我们通过将泵浦激光器锁定到一个独立的稳定的高Q值参考微谐振器和将梳齿间距锁定到一个外部微波振荡器来稳定芯片级Si3N4锁相克尔频率梳。在这种梳状结构中,泵浦激光位移对梳状结构间距变化的影响可以忽略不计。该方案是走向小型化的稳定克尔梳状系统的微谐振器参考可以潜在地集成在芯片上。稳定梳的光学谐波的分数不稳定性受到用于梳间隔锁定的微波振荡器的限制,低于1s的平均时间,并且与泵浦激光器的长期漂移相一致。

英文摘要:

We stabilize a chip-scale Si3N4 phase-locked Kerr frequency comb via locking the pump laser to an independent stable high-Q reference microresonator and locking the comb spacing to an external microwave oscillator. In this comb, the pump laser shift induces negligible impact on the comb spacing change. This scheme is a step towards miniaturization of the stabilized Kerr comb system as the microresonator reference can potentially be integrated on-chip. Fractional instability of the optical harmonics of the stabilized comb is limited by the microwave oscillator used for comb spacing lock below 1 s averaging time and coincides with the pump laser drift in the long term.
