我们分析了瞬逝耦合绝缘体上硅光子线阵列中低功率时空孤子形成的条件。我们已经证实，在存在实际损耗、双光子吸收和高阶色散的情况下可以观察到明显的孤子效应。 $N$ 线阵列中的孤子可以激发 $N$ 个谐振频率，但由于孤子在相应辐射超模上的投影为零，其中一些谐振频率可能会被抑制。这导致从阵列边缘和中心激发的孤子观察到的辐射光谱之间存在显着差异。
We have analyzed the conditions for low-power spatiotemporal soliton formation in arrays of evanescently coupled silicon-on-insulator photonic wires. We have verified that pronounced soliton effects can be observed in the presence of realistic loss, two-photon absorption, and higher-order dispersions. A soliton in an $N$-wire array can excite $N$ resonant frequencies, but some of these may be suppressed due to the soliton having zero projection onto the corresponding radiation supermodes. This results in pronounced differences between the radiation spectra observed from solitons excited at the edge and in the center of arrays.
