We investigate numerically and experimentally the spectral correlation between multiple modulation instability (MI) side lobes in a dispersion oscillating fiber. By leveraging the dispersive Fourier transformation, we acquire instantaneous spectra and investigate the energy correlation between individual MI sidebands through scattergrams. We found that conjugate MI side lobes are strongly correlated while other combinations experience a very low degree of correlation, revealing that parametric processes related to each side lobe pair act quasi-independently.
我们通过数值模拟和实验研究了色散振荡光纤中多个调制不稳定性(MI)边瓣之间的光谱相关性。利用色散傅里叶变换,我们获取了瞬时光谱,并通过散点图研究了各个MI边带之间的能量相关性。我们发现共轭MI边瓣高度相关,而其他组合的相关性非常低,这表明与每个边瓣对相关的参量过程近似独立起作用。
