我们证明，在小型硅光子线阵列中，超模的群速度色散（GVD）可能与单根光子线的群速度色散存在显著差异。这使得在单根光子线具有强正常群速度色散的波长处，能够观察到孤子传播和调制不稳定性。
We demonstrate that the group velocity dispersion (GVD) of the supermodes in a small array of silicon photonic wires can differ dramatically from the single wire GVD. This enables soliton propagation and modulational instability to be seen at wavelengths where single wires have strongly normal GVD.
