| 摘 要： | 用Cu离子交换技术,制备了soda-lime玻璃平面光波导。通过棱镜耦合技术测量了波导的有效折射率,用反WKB方法拟合得到了平面波导的折射率分布。研究发现,离子交换时间和温度2个可控的制备参数对制备的玻璃平面波导特性有较大影响,随着离子交换时间和温度的增加,波导的模式数和波导深度并非随之单调增加,波导模式数随着离子交换时间的增加先增加而后减小,而适当的离子交换时间可以使制备的波导具有最大的模式数和波导深度,且在该条件下增加离子交换温度可以提高Cu离子交换波导的蓝-绿发光强度,宽带发光中心波长在520 nm附近,发光强度取决于样品中Cu+的浓度以及Cu2+的影响。

| Abstract: | Soda-lime glass planar optical waveguides are fabricated by copper ion-exchange technique.The effective indices are measured by prism coupling method and the refractive index profiles of the planar waveguides are reconstructed by inverse WKB method.The properties of the prepared waveguides are affected by the time and temperature of the ion-exchange process.It was found that the modes and depth of the waveguides were not monotonic increasing with the ion-exchange time and temperature increasing,the number o... |
