摘　　要：利用变分原理研究了双芯耦合光纤中具有线性啁啾的光孤子之间的相互作用，得到了啁啾的演化表达式。发现，啁啾增大了孤子之间的相互作用势。本文提出了减弱孤子相互作用的新方案。The interaction between optical solitons with linear chirp in twincore coupling fibers is studied by using variational principle and the expression of the chirp evolving is obtained. The results show the chirp increases the interaction between optical solitons in twincore coupling fibers. We also put forward new schemes about how to decrease the interaction between optical solitons.
