摘　　要：结合科研工作,建立了基于离子交换技术制备平面光波导的设计性综合实验平台。介绍了离子交换技术原理,结合实例描述了Ag^+-Na^+离子交换制备BK7玻璃基平面光波导过程,采用棱镜耦合法测试波导参数,并用逆WKB方法计算拟合波导折射率分布曲线。该实验利于培养学生综合运用知识进行科学研究能力和启发学生创新性思维,实验教学效果良好。Based on the research work, an open and comprehensive experimental platform for the fabrication of planar waveguide by ion exchange technology is established. The principle of ion exchange technology is introduced, and the process of preparing BK7 glass-based planar optical waveguide by Ag^+-Na^+ ion exchange is described. The parameters of waveguide are measured by prism coupling method, and the refractive index distribution curve of waveguide is calculated and fitted by the inverse WKB method. This experiment is beneficial for cultivating students’ ability of scientific research and creative thinking by using knowledge synthetically. The effect of experiment teaching is good.
