利用三维非旁轴近似光束传输法对退火质子交换铌酸锂渐变折射率分布波导中的自镜像效应进行分析与模拟 .在此基础上 ,利用退火质子交换技术在 X切 Y传铌酸锂衬底上进一步制作了 1× 8MMI光功分器 .测试表明器件实现了 1路分成 8路的光功分功能 .
The self-mirroring effect of annealed proton exchange lithium niobate graded index profile waveguide was analyzed and simulated by three-dimensional non-paraxial approximation beam transmission method.On this basis, the annealing proton exchange technology was used to analyze the effect of X- The bottom of the further production of a 1 × 8MMI optical power splitter. Tests show that the device achieved a way into the 8-way optical power points function.
