A light-focusing plastic fiber (LFF) with a parabolic refractive-index distribution was obtained by the continuous heat drawing of the preform prepared from the photocopolymerization of methyl methacrylate with vinyl benzoate. The relation between the preparation conditions and the optical and mechanical properties of the LFFs was clarified. The index profile of the LFFs is found to be scarcely affected by the continuous heat drawing process compared with that of original preforms. The resulting LFF would be suitable for short-distance communication systems due to its attenuation being higher than 10(3) dB/km.
通过对由甲基丙烯酸甲酯与苯甲酸乙烯酯光聚合制备的预制棒进行连续热拉伸，获得了具有抛物线型折射率分布的光聚焦塑料光纤（LFF）。阐明了制备条件与LFF光学和机械性能之间的关系。结果发现，与原始预制棒相比，LFF的折射率分布几乎不受连续热拉伸过程的影响。由于其衰减高于10(3) dB/km，所得的LFF适用于短距离通信系统。
