We report the successful fabrication of a low-loss near-IR waveguide in polycrystalline ZnSe using ultrafast laser inscription. The waveguide, which was inscribed using the multiscan fabrication technique, supported a well-confined mode at 1.55 μm. Propagation losses were characterized at 1.55 μm using the Fabry-Perot technique and found to be 1.07 dB · cm(-1) ± 0.03 dB · cm(-1).
我们报告了使用超快激光刻写成功制备了在多晶 ZnSe 中的低损耗近红外波导。该波导使用多扫描制造技术刻写，在 1.55 μm 处支持良好限制的模式。使用法布里-珀罗技术对 1.55 μm 的传播损耗进行了表征，发现损耗为 1.07 dB·cm(-1)±0.03 dB·cm(-1)。
