用能量为550 keV、剂量为4.0× 10 ~(16)ions/cm ~ 2的质子注入,首次在磁光玻璃(掺Tb ~(3+)的硼硅酸铝玻璃)中制备了平面波导。在260 °C退火1.0 h后,用棱镜耦合法和端面耦合法测量了样品的暗模光谱和近场强度分布。利用SRIM 2010、RCM和FD-BPM分别对平面波导的损伤分布、折射率分布和光传输模式进行了数值计算。通过拉曼光谱和吸收光谱研究了注入对薄膜结构和光学性质的影响。这表明质子注入掺Tb ~(3+)铝硼硅玻璃波导是光纤通信和全光通信中波导隔离器的理想选择。
Planar waveguides in magneto-optical glasses (Tb3+-doped aluminum borosilicate glasses) have been produced by a 550-keV proton implantation at a dose of 4.0×1016ions/cm2for the first time to our knowledge. After annealing at 260 °C for 1.0 h, the dark-mode spectra and near-field intensity distributions are measured by the prism-coupling and end-face coupling methods. The damage profile, refractive index distribution and light propagation mode of the planar waveguide are numerically calculated by SRIM 2010, RCM and FD-BPM, respectively. The effects of implantation on the structural and optical properties are investigated by Raman and absorption spectra. It suggests that the proton-implanted Tb3+-doped aluminum borosilicate glass waveguide is a good candidate for a waveguide isolator in optical fiber communication and all-optical communication.
