摘要

光孤子在光纤通信系统中有着重要的应用。在这里，我们模拟了啁啾高斯双孤子在 1 μm 波段的腔外调制。我们改变了几种不同的孤子参数（包括正交分量的振幅比和时间延迟、投影角、相位差、脉冲啁啾和传播距离），从而有效地改变了初始输入啁啾高斯双孤子的光学光谱和脉冲形状。例如，当光纤调制系统中的两个分支具有相同或不同的光纤长度时，对于正交偏振分量，调制后的啁啾高斯双质子在时域上会表现出明显不同的特性，而相应的光学光谱则没有明显差异。仿真结果揭示了啁啾高斯双孤子的腔外调制效应，进一步探索了光纤激光器腔外孤子整形领域。

Extra-cavity modulation of a chirped Gaussian bisoliton

Optical solitons can find important applications in optical fiber communication systems. Here, we simulate extra-cavity modulation of a chirped Gaussian bisoliton in a 1 μm wavelength band. Several different soliton parameters are varied (including the amplitude ratio and time delay of orthogonal components, the projection angle, phase difference, pulse chirps and propagation distances), to effectively change the optical spectra and pulse shapes of the initial input chirped Gaussian bisoliton. For example, when the two branches in the optical fiber modulation system have the same or different fiber lengths, the modulated chirped Gaussian bisoliton will show obviously different properties in the time domain for orthogonally polarized components, while the corresponding optical spectra have no obvious differences. The simulation results reveal the effects of extra-cavity modulation of the chirped Gaussian bisoliton, which further explores the field of soliton shaping out of a fiber laser cavity.
