在微谐振腔滤波激光器中，当适当平衡系统的慢非线性时，会出现激光腔孤子。在一定条件下，这种光学态可以自发地自出现和恢复，理解它们的鲁棒性对于实际应用至关重要。在这里，我们研究了形成一个键合态，包括一个孤子和一个蓝色失谐的连续波，其共存介导的非线性折射率的色散。我们的实时色散傅里叶变换测量，全面的理论分析的支持下，揭示了存在的两个状态之间的弹性键合，从而增强了孤子的鲁棒性。
Laser cavity-solitons can appear in a microresonator-filtered laser when judiciously balancing the slow nonlinearities of the system. Under certain conditions, such optical states can be made to self-emerge and recover spontaneously, and the understanding of their robustness is critical for practical applications. Here, we study the formation of a bonded state comprising a soliton and a blue-detuned continuous wave, whose coexistence is mediated by dispersion in the nonlinear refractive index. Our real-time dispersive Fourier transform measurements, supported by comprehensive theoretical analysis, reveal the presence of an elastic bonding between the two states, resulting in an enhancement of the soliton’s robustness.
