摘　　要：研究了大尺寸高保偏聚合物光子晶体光纤(polymerPhotonicCrystalFibers,pPCFs)预制棒的化学原位制备技术.采用预聚物浇铸后加热聚合方法,成功制备了具有高保偏性能的光纤预制棒,给出了聚合反应的最佳条件.对此预制棒进行二次拉伸及光学和化学性质的测试表明,该方法得到的预制棒力学结构稳定、光学透明度高,且拉伸所得光纤微结构保持完好、微孔坍塌率低、非固有损耗小.若在聚合反应体系中加入适量的激光染料或其它稀土有机螯合物等物质,可得到具有荧光性的高保偏聚合物光子晶体光纤预制棒,为保偏型聚合物光子晶体光纤激光器的研制提供新材料.The in-situ chemical preparation technology has been explored for the high polarization polymer photonic crystal fibers （pPCFs） preforms. The optimal p have been investigated. From experiments of the secondary draw-stretching of measured results such as microstructure, transmittance, glass transition tempe weight and so on, it is found that these preforms have a lot of characteristics structure, higher optica retaining, less holes col mixed into reaction sys will be a new materials first time for large size olymerization conditions the preforms and the rature （ Tg）, molecular , i. e. steady mechanics 1 transparency,and the pPCFs made by these preforms have ideally microstructure lapse-rate, and lower non-intrinsic loss. If laser dyes and rare earth chelates were tem, the high polarization pPCFs preforms with fluorescence can be gained, which for development of the polarization maintaining PCF lasers.
