摘　　要：利用级数傅立叶方法(FSAT)求解飞秒脉冲在双芯光子晶体光纤(PCF)中的传输方程,分析了双芯PCF中不同耦合色散系数对传输特性的影响。研究表明:只考虑线性耦合色散系数时,脉冲能量在两芯间可持续传递,脉冲形状基本保持不变;考虑模间色散系数的作用后,脉冲在传输小段距离后有明显衰弱,其周期性也遭到破坏。We solve the propagation of fem tosecond pulses in two-core photonic crystal fiber （PCF） by using Fourier series analysis technique （FSAT）,and analyze the affect of difference coupling cofficient dispersion in two-core PCF.Studies have shown that：if consider the linear coupling dispersion only,pluse energy can sustainable transfer between the two-core,and pluse shape unchanged;if we take into account inter-mode dispersion,we find it can cause significant pluse distortion over a short length of a two-core PCF,and it also damaged to the pluse periodic.
