摘　　要：利用棱镜耦合原理与改进的反WKB理论,实现了平面光波导折射率分布的测定 通过该方法获得了离子交换玻璃波导折射率分布曲线,该方法具有操作简单。Based on the principle of prism coupling and improved inverse WKB theory, the refractive-index profiles of planar waveguides were measured. The refractive-index curves of ion exchange glass waveguides were obtained by this way. The method has advantages on convenient operation and accurate results.
