A technique to integrate key functions of a Kerr-microresonator optical frequency comb into one device, i.e., a dual-parallel Mach-Zehnder interferometer (DP-MZI), is proposed. In the technique, a DP-MZI enables the control of carrier envelope offset frequency (f), as well as repetition frequency (f), in addition to generating a stable dissipative Kerr soliton. In experiments, influences on f and f by pump frequency and power modulation via a DP-MZI are investigated, followed by a demonstration of long-term full stabilization of a microresonator soliton comb to a fiber-based optical frequency comb. As another example demonstration, timing jitter of a microresonator soliton comb is significantly suppressed by referencing to a fiber through a two-wavelength delayed self-heterodyne interferometer (TWDI).
提出了一种将克尔微谐振器光学频率梳的关键功能集成到一个器件中的技术，即双平行马赫曾德尔干涉仪（DP-MZI）。在该技术中，DP-MZI除了能产生稳定的耗散克尔孤子外，还能控制载波包络偏移频率（f）以及重复频率（f）。在实验中，研究了通过DP-MZI进行泵浦频率和功率调制对f和f的影响，随后演示了微谐振器孤子梳相对于基于光纤的光学频率梳的长期完全稳定。作为另一个示例演示，通过双波长延迟自外差干涉仪（TWDI）参考光纤，微谐振器孤子梳的定时抖动得到了显著抑制。
