摘要
利用实验数据对梯度型聚合物光纤(棒)中的折射率分布模型进行理论与实验验证,发现该模型对分子体积比大于1的掺杂体系模拟误差较大.通过计算,修正模型中分子体积比的指数参数为1. 1后,模拟误差显著减小,从不大于65% 变为小于20%.这说明分子体积比对界面凝胶聚合形成的梯度型折射率分布影响较大.
The theoretical and experimental validation was made to Lorenz function model of refractive-index distribution in graded-index polymer optical fiber (GI POF) by experimental data. It was found that simulating error is great when molecule bulk ratio is larger than one. According to calculating results, exponent parameter of the molecule bulk ratio in the model was corrected to 1.1, so the simulating error was remarkably reduced from &LE; 65% to < 20%. It showed that influence of the molecule bulk ratio on refractive-index distribution in GI POF is great.
