| 摘 要： | 采用等效传播常数法数值求解负色散波导光纤的弯曲损耗，通过将多包层光纤等效为阶跃光纤，求其等效阶跃光纤的传播常数和等效折射率，从而求得负色散波导光纤的弯曲损耗，在此基础上，以二阶色散补偿光纤为例，给出了色散补偿光纤的弯曲损耗与波长的关系曲线，与实际制造出的负色散光纤的弯曲损耗进行了比较，结果表明理论计算得到的数据与实验数据较一致。

| Abstract: | A formula of the bending loss in negative dispersion optical fiber was presented through calculating the equivalent propagation constant of multi clad fiber. The equivalent propagation constant and equivalent refractive index were obtained by approximating the multi clad fiber to a step fiber. As an example, the dispersion compensation fiber that can compensate dispersion and dispersion slope was introduced. Based on the theoretical analysis, the bending loss curve of negative dispersion fiber was presented, being consistent with the experimental result. |
