在这封信中，通道波导的制作直接紫外写入到体掺锡多组分硅酸盐玻璃。采用不同的激光功率和扫描速率，并进行优化，以避免表面烧蚀。在95 mW的激光功率和10 mm/min的扫描速度下获得了最佳结果，其中估计折射率变化为1.5×10−3，并且使用削减方法测量的衰减损耗为3.3 dB/cm。为了评估激光照射的表面效应，对玻璃端面进行了形态学研究。
In this letter, the fabrication of channel waveguides by direct UV writing into a bulk tin-doped multicomponent silicate glass is presented. Different laser powers and scan rates were employed and optimized to avoid surface ablation. The best results were obtained at a laser power of 95 mW and at a scan speed of 10 mm/min, where a refractive index change of 1.5×10−3 was estimated and an attenuation loss of 3.3 dB/cm was measured using the cutback method. A morphological investigation of the glass end facets was performed in order to assess the surface effect of the laser exposure.
