| 摘 要： | 利用洛仑兹函数对梯度型聚合物光纤(棒)中折射率分布曲线进行模拟,建立折射率分布的洛仑兹函数模型.该模型只需掺杂物的初始浓度、分子体积和聚合温度3个基本参数.利用该模型对各种高折射率的掺杂物掺杂聚甲基丙烯酸甲酯(PMMA)制备的梯度型聚合物光纤中的折射率分布进行了预测,发现掺杂物的折射率比分子体积对折射率梯度的影响更大;惰性掺杂物中二苯硫(DPS)掺杂效率最高;共聚掺杂物中苯甲酸乙烯酯(VB)掺杂效率最高.

| Abstract: | Refractive index distribution of gradient index polymer optical fiber(GI POF) was simulated by Lorenz function and model of refractive index distribution was found firstly, which included three basic parameters: initial concentration, molecule bulk of dopant monomer and polymerization temperature. The refractive index distribution of GI POF adulterated by kinds of high refractive index dopant monomer in PMMA was predicted by the Lorenz function model. It was found that effect of dopant monomers refractive index on gradient index was larger than that of molecule bulk; adulterate efficiency of diphenyl sulfide(DPS) was the highest in kinds of inertia dopant monomers; and adulterate efficiency of vinyl benzoate(VB) was the highest in kinds of co polymerization dopant monomers. |
