【摘要】 针对现有制备方法对梯度型聚合物光纤(GI-POF)折射率分布(RID,直接影响带宽)的调控能力有限的特点,提出了一种制备GIPOF预制棒的新方法,可以实现对RID的自如调控。通过理论计算阐述了这种方法制备预制棒时RID的调控方法。结果表明,制备预制棒时所用物料的层数越多,预制棒的RID越接近理想分布,最终实际所得预制棒的RID与理论计算十分一致。更多还原

【Abstract】 In view of the limited ability of existing methods of preparation of graded index polymer optical fiber(GI-POF) to regulate the refractive index distribution (RID), which had strong effect on the bandwidth, a new method of the preparation of GI-POF preform was proposed in this paper, which could regulate the RID freely. The regulating method was explained by theoretical calculation. The results indicated the RID of GI-POF preform approached to the optimal distribution gradually with the increase ofthe layers of polymer, and the RID of the preform prepared was in accord with the theoretical calculation well.更多还原
