| 摘 要： | 基于流变学原理和质量传递原理的分析，建立了一个能够描述渐变型聚合物光纤（GIPOF）共挤扩散制备过程的数学模型。该模型采用基于温度和掺杂剂浓度修正的Carreau黏度方程，利用计算流体动力学软件Fluent模拟求解出拉丝后光纤折射率分布。以聚甲基丙烯酸甲酯为芯皮层原料、苯硫醚为掺杂剂制备了GIPOF，并通过聚焦法测得光纤折射率分布。模拟结果与实验结果基本相符，表明该模型可用来预测和控制光纤折射率分布情况。

| Abstract: | Based on an analysis of rheology and mass transport principle, a mathematical model was formulated for describing the co-extrusion and diffusion process of graded index polymer optical fiber (GI POF). Using the Carreau viscosity equation, modified according to temperature and dopant concentration, was adopted in the calculation with computer fluid dynamic software-Fluent to obtain the refractive index profile of GI POF. GI POF was prepared using polymethyl methacrylate (PMMA) as core and clad,diphenyl sulfide(DPS) as the dopant. The refractive index profile of GI POF was measured using focusing method. The simulated data were generally consistent with those of experiments. |
