Optical waveguides have been obtained by field-assisted Cu(+)-Na(+) exchanged on glass. The refractive index profiles of the waveguides are determined by means of the prism-coupling technique and Chiang's method [J. Lightwave Technol. LT-3, 385 (1985)], and they correlate with the index profile calculated as a function of the glass composition. The composition profile is examined with the aid of a scanning electron microscopy with energy-dispersive x-ray analysis, and the diffusion process is explained by the one-dimensional diffusion equation.
通过场辅助在玻璃上进行Cu(+) - Na(+)离子交换已获得光波导。光波导的折射率分布通过棱镜耦合技术和蒋氏方法[《光波技术杂志》LT - 3, 385 (1985)]来确定，并且它们与根据玻璃成分计算出的折射率分布相关。借助带有能量色散X射线分析的扫描电子显微镜来检查成分分布，并且用一维扩散方程来解释扩散过程。
