微结构聚合物光纤(MPOF)以其成本低廉、制备简单以及微孔结构的灵活控制性而产生了许多新的光学特性,并作为普通聚合物光纤的替代物,近来取得了快速的发展。MPOF商用化的障碍在于光纤的切割和端面低损耗耦合处理。从实验上研究了MPOF的端面切割工艺,找到了影响端面切割效果的因素,包括:光纤拉伸条件、切割刀片的温度、切割光纤的温度等,并最终得到了光学性能较好的微结构聚合物光纤切割端面。

Microstructured polymer optical fiber (MPOF) are rapidly developing as an alternative to conventional polymer optical fiber. They are cheaper and simpler to make,and aslo have a wide varity of new optical properties through tailoring the hole structure imposed on the preform and maintained within the final fiber. However,one important issue that needs resolution to facilitate successful commercialisation is cleaving of the fiber to form an optical ending face for coupling. The impact of the following parameters is considered in cleaving microstructured polymer optical fibers:fiber drawing conditions;temperature of cutting blade,and fiber temperature during cleaving,etc. Optically acceptable MPOF ending faces can be produced by employing a “hot blade/hot fiber” combination.
