耗散孤子的频率转换与宽带光频率梳的产生相关，具有数百千兆赫兹的齿间距是一个热门的挑战，持有在精密光谱学和数据处理的实际应用的关键。在这个方向上的工作是由非线性和量子光学的基本问题。在准相位匹配微谐振腔中，我们研究了近红外波段二次谐波泵浦下的耗散双色亮-亮和暗-暗孤子。我们还发现了与脉冲前沿运动和碰撞有关的呼吸状态。孤子制度被发现是典型的在轻微的相位失配的谐振器，而相位匹配的揭示了更广泛的，但不相干的光谱和高次谐波的产生。本文报道的孤立子和呼吸效应存在于谐振线的负倾斜中，这只有通过二阶非线性的主要贡献才可能实现。提高集成光子器件中产生的光信号的转换效率、相干性和光谱带宽是当前的一个重要挑战。在这里，作者提出了他们的观察双色耗散孤子，呼吸子和频率梳产生的二次谐波产生的锂酸盐环形微谐振器。
Frequency conversion of dissipative solitons associated with the generation of broadband optical frequency combs having a tooth spacing of hundreds of giga-hertz is a topical challenge holding the key to practical applications in precision spectroscopy and data processing. The work in this direction is underpinned by fundamental problems in nonlinear and quantum optics. Here, we present the dissipative two-colour bright-bright and dark-dark solitons in a quasi-phase-matched microresonator pumped for the second-harmonic generation in the near-infrared spectral range. We also found the breather states associated with the pulse front motion and collisions. The soliton regime is found to be typical in slightly phase-mismatched resonators, while the phase-matched ones reveal broader but incoherent spectra and higher-order harmonic generation. Soliton and breather effects reported here exist for the negative tilt of the resonance line, which is possible only via the dominant contribution of second-order nonlinearity. Boosting conversion efficiency, coherence and spectral bandwidth of optical signals generated in integrated photonic devices is an important current challenge. Here, the authors present their observations of two-colour dissipative solitons, breathers and frequency combs resulting from second-harmonic generation in lithium-niobate ring microresonators.
