The fabrication of planar waveguides by a constant-current thermal poling procedure in multicomponent glasses rich in alkali or alkaline earth ions is described. Near the anode, the dc electric field applied to the substrate separates the mobile cations into regions according to their mobility. Each region presents a different refractive index, allowing a waveguide to be formed. This method produces waveguides with an index increase greater than 10(-2) in soda-lime glass with no external ion source, and the waveguides are buried beneath the substrate surface without an additional step.
描述了在富含碱金属或碱土金属离子的多组分玻璃中通过恒流热极化工艺制造平面波导的方法。在阳极附近，施加到衬底上的直流电场根据移动阳离子的迁移率将它们分离到不同区域。每个区域呈现不同的折射率，从而形成波导。该方法在无外部离子源的钠钙玻璃中产生折射率增加大于10（-2）的波导，并且波导无需额外步骤即可埋入衬底表面之下。
