双折射光纤中损耗对孤子相互作用的影响

Influence of the Fiber Loss on Interaction between Optical Solitons in Birefringent Fibers

利用变分原理研究了有损耗的情况下双折射光纤中孤子间的相互作用，发现损耗减弱了孤子间的相互作用，但同时使光纤中继间隔缩短，这为实际应用中如何控制孤子间的相互作用提供了一定的理论依据。

The interaction between optical solitons in birefringent fibers with loss is studied by using variational principle. The result shows that the loss reduces the interaction and shortens the repeater spacing. It provides a practical method to control the interaction between optical solitons.
