论文摘要
微孔子中的八度频率梳子对于自我引用至关重要。然而，由于分散体的有害影响，小型和高度重复利率微孔子很难在广泛的频率范围内实现完美的孤子模型。在这里，我们研究了由二百个模式组成的孤子状态的稳定性。我们报告了在狭窄的引人入胜的范围内快速和慢的孤子共存，该范围在两侧都被呼吸器状态包围。我们将呼吸梳分解为具有不同载体包络偏移频率的子序列的序列。大型失调的呼吸器具有与整个微孔子延伸的扰动相关的高频率振荡。小小的引起呼吸器会产生圆锥芯上定位的振荡，并可以进行时期的分叉，从而触发一系列强烈的亚果。
Octave-wide frequency combs in microresonators are essential for self-referencing. However, it is difficult for the small-size and high-repetition-rate microresonators to achieve perfect soliton modelocking over the broad frequency range due to the detrimental impact of dispersion. Here we examine the stability of the soliton states consisting of one hundred modes in silicon-nitride microresonators with the one-THz free spectral range. We report the coexistence of fast and slow solitons in a narrow detuning range, which is surrounded on either side by the breather states. We decompose the breather combs into a sequence of subcombs with different carrier envelope offset frequencies. The large detuning breathers have a high frequency of oscillations associated with the perturbation extending across the whole microresonator. The small detuning breathers create oscillations localised on the soliton core and can undergo the period-doubling bifurcation, which triggers a sequence of intense sub-combs.
