极化聚合物材料具有非线性系数高、电容率低、易加工处理、与现有集成工艺相兼容等特点，因而在集成光学特别是光通信器件领域有着广阔的应用前景。而最近新兴的无机/有机杂化材料，由于兼备聚合物的柔韧性、高透光性和无机物的热稳定性等特点，而备受材料界关注。本文的主要工作就是制备两种体系极化聚合物薄膜，包括主客体掺杂型体系和有机/无机杂化型体系，并运用光漂白工艺制备出以杂化型薄膜为芯层的Y型光波导。实验中首先以分散红1（DR1）为生色团，制备基体为PMMA的主客体掺杂型极化聚合物体系。DR1含量为10wt%的聚合物PR-10的Tg只有94℃，而PMMA的Tg为105℃；并以PR-10为例，对主客体掺杂型极化...There were advantages, for nonlinear optical (NLO) poled polymer materials, of large nonlinear optical coefficient, low permittivity, easy processing and monolithic integration.It was thus expected that they played an important role in the field of integrated optics, especially high performance photonic devices, such as high-speed optical switches, tunable filters and broadband optical modulators....学位：工学硕士院系专业：化学化工学院材料科学与工程系_材料学学号：1932005130195
