聚合物光纤光栅制备及应用进展

Fabrication and Application of Polymer Optical Fiber Gratings:A Review

近年来,聚合物光纤因其体积小、质量小、柔软、成本低等诸多优点,以及不同于石英光纤的生物相容性等优良特性,在传感及通信等领域逐渐受到了重视。系统介绍了包括聚甲基丙烯酸甲酯、环烯烃共聚物、环烯烃均聚物以及聚碳酸酯等的聚合物光纤组成材料,基于不同波段的刻写激光源如248 nm、266 nm、325 nm等的光栅制备技术,以及包括相位掩模板刻写、飞秒激光直写技术以及飞秒激光双光子聚合刻写技术等的光栅刻写技术。最后,回顾了近些年聚合物光纤光栅在传感及通信领域的研究进展,并进行了总结和展望。

In recent years, polymer optical fibers have received increasing attention in the fields of sensing and communication because of their small size, light weight, softness, low cost, and excellent characteristics such as biocompatibility compared with silica optical fibers. We analyze various materials for polymer fibers, including polymethyl methacrylate(PMMA), ring olefin copolymer, ring olefin polymer, and polycarbonate;different grating fabrication techniques, including those using lasers with different wavelengths(e. g., 248, 266, and 325 nm);and different engraving techniques, including phase mask, femtosecond laser direct writing, and femtosecond laser twophoton polymerization. In addition, we review the research progress in polymer optical fiber grating in the fields of sensing and communication in recent years and summarize the major developments.
