源啁啾飞秒孤子间相互作用的数值研究

Numerical Research of Femtosecond Soliton Interaction with Chirp from Optical Source

对源啁啾飞秒孤子间的相互作用进行了数值研究 ,结果表明源啁啾飞秒孤子间的相互作用比无源啁啾时更加严重 ,会在通信系统中造成更大的误码率。研究结果还表明 ,不等幅传输法在一定程度上可有效地抑制源啁啾飞秒孤子间的相互作用。

The influence of optical source chirp on femtosecond soliton interaction is studied numerically. Results show that femtosecond soliton interaction with chirp fromoptical source is more serious than that without optical source chirp. The former can cause larger error code rate in soliton communication systems. The results also show unequal amplitude method can reduce the interaction between femtosecond soliton in the presence of optical source chirp in a certain degree.
