Optical parameter accurate measurement for polymer waveguide amplifier materials and the device fabrication

使用甲基丙烯酸甲酯(MMA)和甲基丙稀酸环氧丙酯(GMA)共聚,并加入双酚A环氧树脂(bis-phenol-Aepoxy)来调节折射率,制备了无源波导材料。使用铒的配合物ErYb(DBM)2MA和MMA、GMA共聚,再加入双酚A环氧树脂调节折射率,制备了用于光波导放大器有源波导材料。使用椭偏仪对无源和有源的聚合物薄膜的折射率、消光系数和厚度进行了测量。无源的聚合物折射率随着环氧树脂含量的增加而线性增加。铒的配合物共聚进聚合物基质中使1.55μm波段折射率和消光系数增加。无源和有源波导材料的折射率可调节范围在大约在1.48～1.53,厚度可调节范围大约在1～6μm。用有源聚合物材料作芯层、无源聚合物材料作包层,制备了1.55μm单模有源波导,并得到了圆形的近场光斑。

By using polymerizing Methyl Methacrylate（MMA） and Clycidyl Methacrylat （GMA） and adding bisphenol-A epoxy to adjust the refractive index,the passive waveguide material was prepared; By using polymerizing the Erbium complex ErYb（DBM） 2 MA, Methyl Methacrylate （MMA） and Clycidyl Methacrylat （GMA） and adding bisphenol-A epoxy to adjust the refractive index,the active waveguide material for the waveguide amplifiers was prepared. The refractive index, the extinction coefficient and the thickness of these passive and active polymer films were measured using ellipsometer, The results show that the refractive index of passive polymer linearly increases with the increasing concentration of the epoxy;the copolymerization of Erbium complexes into polymer matrix makes the refractive index and the extinction coefficient increase in the 1.55μm region;the passive and active materials have an adjustable range 1.48-1.53 for the refractive index,and 1-6μm for the thickness. The 1.55μm active single mode waveguides were fabricated using the active polymer as core and passive cladcling polymer as cladding, and the circular near field was obtained.
