论文摘要
在许多应用中，例如高容量光学通信等许多应用中，宽带Kerr梳子具有平坦的梳状光谱曲线。在这里，我们提出了用于高级分散工程的新型同心双环微孔子（DRM），以量身定制梳状光谱轮廓。色散不仅可以通过DRM的横截面来灵活地设计，还可以通过同心双环微孔子之间的间隙来灵活地设计，该差距提供了一条新的路径，以几何控制Soliton Kerr Combs的光谱轮廓。数值覆盖了具有上频谱平面度的八度散开耗散唯一的Kerr Soliton梳子，从电信带覆盖到中红外（MIR）带宽1265 nm（99.82 THZ）的中红外（MIR）带区域。我们的结果有望充分了解DRM中混合模式中的非线性动力学，这有助于控制宽带梳形成。
Broadband Kerr combs with a flat comb spectral profile are expected in a number of applications, such as high-capacity optical communication. Here, we propose novel concentric dual-ring microresonators (DRMs) for advanced dispersion engineering to tailor the comb spectral profile. The dispersion can be flexibly engineered not only by the cross-section of the DRMs, but also by the gap between concentric dual-ring microresonators, which provides a new path to geometrically control the spectral profile of the soliton Kerr combs. An octave-spanning dissipative Kerr soliton comb with superior spectral flatness has been achieved numerically, covering from the telecommunication band to the mid-infrared (MIR) band region with a -40 dB bandwidth of 1265 nm (99.82 THz). Our results are promising to fully understand the nonlinear dynamics in hybrid modes in DRMs, which helps control broadband comb formation.
