摘　　要：本文研究并制作了光纤双圆锥体滤波器，给出了耦合模总相位差与滤波性能之间的关系，讨论了推的对称性对滤波器峰值传输的影响，对不同结构的锥体谱特性进行数值计算以验证分析结果，最后给出了实验结果对照．This paper studied and manufactured the filter of fiber biconical taper. The relationship between the filter performance and total phase difference of couple-mode was presented. The influence of the taper symmetry on filter peak transmission power was discussed. The spectral chracteristics of tapers with different structures were numerically calculated in order to prove analytic results and were compared with experimental results.
