脊形波导耦合的光纤阵列设计

Design of Fiber Array Coupled with Ridge Waveguides

分析了单模光纤与脊形波导的耦合模理论,讨论了其模式特点、最佳耦合条件。在此基础上,计算并设计出满足最佳耦合条件的光纤阵列V 型槽宽度。所设计的光纤阵列在对光纤提供高精度定位的同时,又能保证其与脊形波导的高效率耦合。

The mode characteristics of single-mode optical fiber and ridge waveguide are analyzed based on the coupled mode theory.The reasonable width of V-groove structure of fiber array is finally calculated and designed under optimal coupling condition between single-mode optical fibers and ridge waveguides.So fiber array not only provides optical fiber with high precision positioning,but also ensures the optimal coupling efficinecy to ridge waveguides.
