摘　　要：将反WKB方法和余误差函数拟合法相结合,分析了Ag+-Na+离子交换平面光波导的折射率分布,建立了光波导折射率分布与离子交换工艺参数之间的联系.得到扩散系数D与扩散温度T呈指数关系,衬底折射率改变量Δn与Ag+的浓度呈线性关系的结果.This paper determined the refractive index profile of ion-exchanged slab waveguides by IWKB method and complementary function fitting. Some conclusions of the relation between index profile and process parameters on the basis of abundant experiments are drawn: (1) It shows exponential relationship between diffusion coefficient and temperature. (2) The increase of refractive index is linear with concentration of ionic silver in salt bath.
