本文介绍了在玻璃中通过场辅助离子交换产生条形波导折射率分布的理论研究，并与在特殊玻璃类型中通过Ag+-Na+交换获得的实验结果进行了比较。计算掩模开口的周期性结构的内部电场，并将其应用于通过单个掩模开口的离子交换过程以及使用所谓的保护带的过程。这些保护带特别适合于阶跃折射率光纤的轮廓匹配。与渐变折射率光纤的匹配需要埋入步骤，这是用合理的物理假设建模的。
The paper presents both the theoretical investigation of refractive index profile generation of stripe waveguides by field‐assisted ion exchange in glass and a comparison with experimental results obtained by Ag+‐Na+ exchange in a special glass type. The internal electric field of a periodical structure of mask openings is calculated and applied to ion‐exchange processes through a single mask opening as well as to processes using so‐called guard bands. These guard bands are especially suitable for profile matching to step index fibers. Matching to graded index fibers requires burying steps, which are modeled with plausible physical assumptions.
