三光子吸收效应对孤子对传输的影响

The Effect of Three-photon Absorption on the Couple of Solitons in Propagation

用分步傅里叶变换法求解含三光子吸收效应的光孤子NLS方程,研究了三光子吸收效应对孤子对在传输中相互作用的影响。研究发现,在特定条件下,三光子吸收效应能使孤子对无离合地平行传输。

The properties of propagation of couple of solitons including threephoton absorption were studied numerically.The results show that threephoton absorption can make couple of solitons transmit parallel.
