摘　　要：基于模式耦合理论,研究了呈一字型排列的多根平行单模光纤间的功率转移,分析了光纤间距对耦合系数和功率转移的影响,给出了三根平行单模光纤耦合方程的解,针对不同的初始条件进行了比较分析.数值计算表明,呈一字型排列的多根平行单模光纤间的功率成一定周期转移·Based on a coupled mode theory, the power transfer among many parallel single-mode optical fibers formed into ＂-＂ has been investigated. The analysis shows that the distance between each of the N fiber centers has an effect on the coupling coefficient and power transfer. The solution of the coupledequation for three parallel single-mode optical fibers has been given, and is comparatively studied for different initial conditions. Numerical simulations show that power transfer will be periodical when coupling occur among many parallel single-mode optical fibers formed into ＂-＂.
