标题： Analysis of high-order dispersion on ultrabroadband microresonator-based frequency combs

摘要： 我们数值研究了高阶色散对基于微谐振器的光学频率梳的时间和光谱特性的影响。 矩方法被用于研究腔内孤子的时间动力学。 理论和数值结果表明，时间偏移是由高奇数阶色散引起的，而不是高偶数阶色散。 通过分析腔内切连科夫辐射，仔细阐明了高阶色散对频率梳包络的作用。 我们进一步证明，可以通过使用具有多个零色散波长的色散轮廓来设计超宽带光学频率梳的光谱包络。 显示英文摘要

摘要： We numerically investigate the influence of high-order dispersion on both temporal and spectral characterizations of microresonator-based optical frequency combs. The moment method is utilized to study the temporal dynamics of intracavity solitons. The theoretical and numerical results indicate the temporal shifts are induced by high-odd-order dispersion rather than high-even-order dispersion. The role of high-order dispersion on the frequency comb envelopes is carefully elucidated through analyzing the intracavity Cherenkov radiations. We further demonstrate that the spectra envelope of an ultrabroadband optical frequency comb can be engineered by using dispersion profiles with multiple zero dispersion wavelengths.
