论文摘要
我们报告了1550 nm和1064 nm频段中的低功率，八度带宽，单线微音式频率梳的全面研究。我们的实验利用了完全集成的二氮Kerr微孔子，我们展示了直接的孤子生成，其可用的分布式bragg-reflector激光器可提供少于40 MW的芯片耦合激光功率。我们报告了孤子热动力学的测量结果，并证明了与微孔子的热时间尺度一致的激光频率控制如何有助于稳定八度孔孔combs。此外，由于Soliton梳子是通过甲状管内部磁场的基本线性和非线性动力学完全描述的，因此我们演示了建模与八度带宽梳子的产生之间的紧密联系。我们的实验通过集成 - 光音技术推进了自我引用的频率梳子的开发，以及在近红外跨红外的梳子激光源，具有数十张Terahertz脉冲带宽。
We report a comprehensive study of low-power, octave-bandwidth, single-soliton microresonator frequency combs in both the 1550 nm and 1064 nm bands. Our experiments utilize fully integrated silicon-nitride Kerr microresonators, and we demonstrate direct soliton generation with widely available distributed-Bragg-reflector lasers that provide less than 40 mW of chip-coupled laser power. We report measurements of soliton thermal dynamics and demonstrate how rapid laser-frequency control, consistent with the thermal timescale of a microresonator, facilitates stabilization of octave-bandwidth soliton combs. Moreover, since soliton combs are completely described by fundamental linear and nonlinear dynamics of the intraresonator field, we demonstrate the close connection between modeling and generation of octave-bandwidth combs. Our experiments advance the development of self-referenced frequency combs with integrated-photonics technology, and comb-laser sources with tens of terahertz pulse bandwidth across the near-infrared.
