论文摘要
微孔子中的频率转化已彻底改变了现代非线性和量子光学。在这里，当参数转换回到泵谱通过谐振器参数空间中的大域中占主导地位时，我们在微微波NATOR中介绍了多模二次谐波生成的理论。我们证明，该制度中边带的光谱可调性受所谓的Eckhaus不稳定性的离散序列的控制。我们报告了向孤子的过渡和孤子的产生，后者在泵场中具有双脉冲结构。这些孤子存在于双态性间隔和略微弯曲的背景之外。
Frequency conversion in microresonators has revolutionised modern-day nonlinear and quantum optics. Here, we present a theory of the multimode second harmonic generation in microresonators under conditions when the parametric conversion back to the pump spectrum dominates through the large domain in the resonator parameter space. We demonstrate that the spectral tunability of the sideband generation in this regime is governed by a discrete sequence of the so-called Eckhaus instabilities. We report the transition to modelocking and generation of solitons, which have a double-pulse structure in the pump field. These solitons exist outside the bistability interval and on a slightly curved background.
