摘要:

光孤子分子是光孤子的束缚态,它是由引力和排斥作用的平衡而产生的。在从光纤到锁模激光器的系统中观察到的这些现象,为了解孤子之间的基本相互作用和非线性系统的基本动力学提供了新的视角。在这里,我们进入克尔微谐振器的多稳态制度,以产生不同的孤子状态,在相同的光共振泵浦的叠加,并报告发现的异质耗散克尔孤子分子。超快电光采样揭示了这种孤子分子的紧密短程束缚性质,尽管包括不同的振幅,持续时间和载波频率的耗散克尔孤子。除了在解决复杂非线性系统中的孤子动力学的意义,这种异质孤子分子产生相干频率梳,其不寻常的模式结构可能会在计量学和光谱学中找到应用。

英文摘要:

Optical soliton molecules are bound states of solitons that arise from the balance between attractive and repulsive effects. Having been observed in systems ranging from optical fibers to mode-locked lasers, they provide insights into the fundamental interactions between solitons and the underlying dynamics of the nonlinear systems. Here, we enter the multistability regime of a Kerr microresonator to generate superpositions of distinct soliton states that are pumped at the same optical resonance, and report the discovery of heteronuclear dissipative Kerr soliton molecules. Ultrafast electrooptical sampling reveals the tightly short-range bound nature of such soliton molecules, despite comprising dissipative Kerr solitons of dissimilar amplitudes, durations and carrier frequencies. Besides the significance they hold in resolving soliton dynamics in complex nonlinear systems, such heteronuclear soliton molecules yield coherent frequency combs whose unusual mode structure may find applications in metrology and spectroscopy.
