Chip-scale optical frequency combs have attracted significant research interest and can be used in applications ranging from precision spectroscopy to telecom channel generators and lidar systems. In the time domain, microresonator based frequency combs correspond to self-stabilized soliton pulses. In two distinct regimes, microresonators are shown to emit either bright solitons in the anomalous dispersion regime or dark solitons (a short time of darkness in a bright background signal) in the normal dispersion regime. Here, the dynamics of continuous-wave-laser-driven soliton generation is investigated in the zero-group-velocity-dispersion regime as well as the generation of solitons that are spectrally crossing different dispersion regimes. In the measurements, zero-dispersion solitons with multipeak structures (soliton molecules) are observed with distinct and predictable spectral envelopes that are a result of fifth-order dispersion of the resonators. Numerical simulations and the analysis of bifurcation structures agree well with the observed soliton states. This is the first observation of soliton generation that is governed by fifth-order dispersion, which can have applications in ultrafast optics, telecom systems, and optical spectroscopy.

微谐振器中的五次色散孤子频率梳
芯片级光学频率梳引起了人们的广泛研究兴趣，可用于从精密光谱到电信信道发生器和激光雷达系统的各种应用。在时域中，基于微谐振器的频率梳对应于自稳定孤子脉冲。在两种不同的情况下，微谐振器被证明可以在反常色散情况下发射亮孤子，或者在正常色散情况下发射暗孤子（明亮背景信号中的短时间黑暗）。在这里，研究了零群速度色散区域中连续波激光驱动的孤子生成的动力学以及光谱上跨越不同色散区域的孤子的生成。在测量中，观察到具有多峰结构（孤子分子）的零色散孤子具有独特且可预测的光谱包络，这是谐振器五阶色散的结果。数值模拟和分叉结构的分析与观测到的孤子态非常吻合。这是首次观察到由五阶色散控制的孤子产生，可在超快光学、电信系统和光谱学中得到应用。
