摘要:

实现集成光子学的光学频率梳将使更广泛地使用精确的定时信号。在这里,我们探讨的倍频程,克尔微谐振器频率梳的产生,使用混合集成的InP分布反馈激光器和SiN光子集成电路。我们展示了电泵浦和光纤封装的原型系统,使自注入锁定。这种激光器和微谐振器电路的直接集成,而不需要以前使用的介入元件,如光调制器和隔离器,需要理解倍频程克尔孤子的自注入锁定动力学。特别是,系统架构必须调整到强耦合的微谐振器后向散射和激光微谐振器的频率失谐,我们发现这里。我们的工作说明了实现集成光子学的自参考频率梳的关键考虑因素。

英文摘要:

Implementing optical-frequency combs with integrated photonics will enable wider use of precision timing signals.Here, we explore the generation of an octave-span, Kerr-microresonator frequency comb, using hybrid integration ofan InP distributed-feedback laser and a SiN photonic-integrated circuit. We demonstrate electrically pumped and fiber-packaged prototype systems, enabled by self-injection locking. This direct integration of a laser and a microresonatorcircuit without previously used intervening elements, like optical modulators and isolators, necessitates understand-ing self-injection-locking dynamics with octave-span Kerr solitons. In particular, system architectures must adjust tothe strong coupling of microresonator back-scattering and laser-microresonator frequency detuning that we uncoverhere. Our work illustrates critical considerations towards realizing a self-referenced frequency comb with integratedphotonics.
