中文摘要: 聚合物有源光子学器件是全光集成领域的研究热点。同时提高透明聚合物中局部微区域的折射率和光学增益特性,是在聚合物中实现可集成的有源光子学器件的关键。本项目拟采用紫外曝光技术与多光子加工技术相结合的方法,在透明聚合物中形成微纳尺度的包埋型聚合物互穿网络结构,并在其中原位生成半导体纳米粒子,同时赋予其高折射率和荧光发光特性。探索材料种类和激光加工参数对聚合物互穿网络结构的微区尺寸、成分的空间分布以及网络交联密度等参数的影响。进一步,考察半导体纳米粒子的尺寸、分布、浓度以及发光特性等参数对聚合物互穿网络结构的依赖性。在此基础上,系统地研究含有半导体纳米粒子的聚合物互穿网络结构中光与物质相互作用原理,为聚合物有源光子学器件的构筑和集成提供新的研究方法和技术途径。本项目研究工作具有原始创新性,将对全光集成技术的发展产生重要的推动作用。

英文摘要: Polymeric active devices are the hot topic in the all-optical integration technology. The key point to realize the active devices in polymers is simultaneous enhancement of the refractive index and optical gain properties. The studies of this project will change the refractive index and optical properties of the local regions embedded inside the transparent polymer by introducing semiconductor nanoparticles using in-situ synthesis into the interpenetrated polymer network, which is fabricated via the combination of the UV and multi-photon induced polymerization. We will investigate the influence of the materials and laser parameters on the size, component, and cross-linking intensity of the interpenetrated polymer network. Furthermore, we will study the dependence of the size, distribution, concentration and optical properties of the semiconductor nanoparticels on the interpenetrated polymer network. On the basis of this, we will demonstrate the interaction of the optics and matter in the interpenetrated polymer network containing semiconductor nanoparticles. The studies in this project will provide novel ideas and important strategies for the development and integration of the polymeric active devices, and promote the development of the all-optical integration.
