摘要
利用Cu+-Na+离子交换技术制备了玻璃平面光波导,在632.8 nm波长下,用棱镜耦合技术测量出所制备波导的有效折射率,利用反WKB方法确定了平面光波导的折射率分布,并对折射率分布进行了函数拟合,近似符合高斯分布.求出了所制备玻璃平面光波导在580℃的扩散系数为De≈2.223×10-15 m2/s.
Abstract
Planar optical waveguides were fabricated by Cu +-Na + ion-exchange on soda-lime glass substrate. The effective refractive index was measured by prism-coupling technique at the wavelength of 632.8 nm. Refractive index profile was determined by Inverse-WKB method. Results are compared with mathematical solutions, the best fit to the index experiment data is Gauss function. Therefore, the diffused coefficient of Cu +-Na + ion-exchange at 580℃ is De≈2.223×10 -15 m 2/s.
