Its wave propagation properties in symmetry and asymmetry structure are analyzed by 3-D EBPM including the analysis and study of the influence of refractive index to wave propagation. The bend fiber-slab is also studied in this paper and point that the influence of the refractive index of the substrate to wave propagation in fiber-slab is very important. The calculating results agree with the results of the test.

本论文利用三维显式光束传播法很方便地分析了对称、非对称光纤—光波导复合结构中光波的传输问题，包括光纤折射率的大小、光波导折射率的大小对光波传输的影响等在内的主要内容；随后又研究了光纤弯曲时光波导包层折射率对光纤内能量功率大小的影响，计算结果和实验结果吻合。
