摘　　要：文章基于单模阵列光纤与平面光波导对准的理论模型,对在精确对准过程中常见的两种位置搜索法(爬山法和模式搜索法)进行了仿真模拟实验。仿真实验证明模式搜索法可以更快地搜索到最大光功率值,算法收敛性明显好于爬山法。On the basis of the theoretical model for the alignment of single-mode optical fiber array with the planar optical waveguide, simulations of two position search methods, i.e. hill climbing method and pattern search method, commonly used in accurate alignment processes are conducted. The results indicate that the maximum optical power value can be faster searched by the pattern search method and the convergence of the algorithm is significantly higher than by the hill climbing method.
