论文摘要
第三谐波生成过程的相匹配可用于将辐射从Kerr微孔子发射扩展到远离泵波长的新光谱区域。在这里，我们为基于耗散和非线性$χ^{（3）} $的型腔系统提供了一个理论平均模型，该模型在基本和第三谐波之间具有参数耦合。我们研究了具有广泛带宽的相匹配梳子的时间色散双弯曲生成，并报告了访问多稳态的条件，该条件同时支持两种类型的耦合亮腔孤子。这些Bistable腔孤子共有相同的泵功率和频率不谐的，同时具有不同的田间组件的不同振幅。第三谐波生成频率梳子可以允许电信泵激光源同时直接访问近红外和可见区域，这可能是对光学时钟和传感应用的开发有利的。
Phase-matching of the third-harmonic generation process can be used to extend the emission of radiation from Kerr microresonators into new spectral regions far from the pump wavelength. Here, we present a theoretical mean-field model for optical frequency combs in a dissipative and nonlinear $χ^{(3)}$-based cavity system with parametric coupling between fundamental and third-harmonic waves. We investigate temporally dispersive dual-comb generation of phase-matched combs with broad bandwidth, and report conditions for accessing a multistable regime that simultaneously supports two types of coupled bright cavity solitons. These bistable cavity solitons coexist for the same pump power and frequency detuning, while featuring dissimilar amplitudes of their individual field components. Third-harmonic generation frequency combs can permit telecom pump laser sources to simultaneously directly access both the near-infrared and the visible regions, which may be advantageous for the development of optical clocks and sensing applications.
