摘　　要：　从理论上推导了2×2单模光纤耦合器耦合系数的计算公式。然后结合实际制作条件进行了合理的近似,从而分析了在实际制作中两条拉锥光纤之间的水平间距d0及拉锥基座垂直偏差y对于耦合器耦合系数的影响。The formula for calculating the coupling ratio of 2×2 single mode fiber couplers is derived. The rational approximation of this formula is made according to the practical fabrication conditions. On this basis we analyze the effects of horizontal space d0 between the two tapered fiber and vertical space y between the two tapering bases on the coupling ratio of fiber couplers in practical fabrication.
