研究了可作为塑料光纤与石英光纤连接器件的锥形塑料光纤过渡器的制作方法及性能测试。采用重力垂直熔融拉锥法制作锥形塑料光纤过渡器
并研究其在实验室条件下的最佳工艺参数。重复实验发现
当加热电压为6.0 V
加热区中心温度在214 ℃附近
拉伸力为1.40 g左右时
塑料光纤的拉伸过程容易控制
拉伸后的塑料光纤表面具有良好的光学质量。测试显示锥形塑料光纤的透射率随着锥度的增大而减小
表面显微形貌良好
出射模式数明显减少
出射模模场强度集中在低阶模部分
可见光透射谱在400~500 nm的损耗加大。对测试结果的分析表明
采用重力垂直熔融拉锥法可以制备性能优良的锥形塑料光纤过渡器
实验得到的最佳工艺参数可为POF连接器、耦合器的实际生产提供参考。
Plastic Optical Fiber(POF) tapered connectors can be used as the connection devices of POFs and quartz optical fibers
so this paper introduces the fabrication and performance of tapered POF connectors. A gravity vertical fused elongated taper method is used to fabricate the tapered POF connectors
and the optimal technical parameters are also obtained under the laboratory conditions. It is found that the process of POF stretching is easy to be controlled and the tapered POF connectors show its good optical quality when the control voltage is 6.0 V
the heating zone center temperature is about 214 ℃ and the stretch strength is about 1.40 g. Experiments prove that the transmission rate of the POF with a fine surface morphology decreases with increasing taper angles
its out light modes decreases
the out light mode intensity is on the low rank modes
and the losses from the visible light transmission spectrum increases in the ranges of 400 to 500 nm. These results show that the gravity vertical fused elongated taper is a effective way to fabricate the tapered POF connectors
and the obtained technical parameters from the experiments can provide the references for the actual productions of POF connectors or POF couplers.
