摘要
针对太赫兹聚合物光子晶体光纤的应用需求, 对聚合物光纤的制备材料、预制棒制备、拉伸工艺等关键制备工艺进行了研究.分析了聚合物材料的特性, 并进行实验验证, 结果表明ZEONEX材料的吸收系数低于3 cm-1, 吸水性低于0.01%, 玻璃化转变温度和分解温度分别高达136℃和420℃, 在太赫兹光纤制备中具有优良性能.预制棒制备和光纤拉伸的工艺方面, 在注塑法的基础上改进了模具系统, 使用可控的微压拉丝技术, 在10~200 Pa范围内可实现±1.5 Pa的微压差精确控制, 较大程度上提高了光纤预制棒的成品率和光纤的形变控制, 有望制备出高空气填充率的聚合物光子晶体光纤.
Abstract
The technologies of fabricating polymer photonics crystal fiber to suit the application needs of terahertz transmission were studied, which were related to material selecting, fiber preform fabrication and fiber drawing. According to the analyzation of optical polymers’ properties and the experimental verification, ZEONEX has low absorption of less than 3 cm-1 in Terahertz waves, low water absorption of less than 0.01%, high glass transition tempreture and decomposition temperature of 136℃ and 420℃ respectively. As for fiber preform fabrication and drawing, the model system was improved based on injection moulding, and drawing technology of Pascal level pressure auto-control was initially invented. The controlled value oscillations is no more than 1.5 Pa in the range of 10~200 Pa. Therefore the preform quality and reliability are promoted and fiber microstructure is effectively controlled. With the proposed technology it is hopeful of producing high air filling factor polymer photonics crystal fiber.
