Optical materials for photonic applications

光学工程中的应用材料仍然是阻碍技术发展的主要瓶颈。必须努力开发新材料，研究其制作，并根据可预见的技术对其进行表征。我的研究小组正在研究不同类型的材料，如光聚合物、染料-掺杂聚合物、硫化物和光子带隙晶体。聚合物材料为光学工程行业面临的问题提供了非常优雅和廉价的解决方案。这些材料可用于制造光子元件、生物光子学和农业光子学传感器等。硫系化合物薄膜仍被认为是许多光学应用的有前途的材料。我们在溶胶-凝胶制造和金属有机沉积材料方面发展了专业知识，这些材料可以带来取向的晶体结构。利用聚合物纳米球制作的光子带隙已经形成，但这些晶体的工艺和质量还有待研究。拟议的研究计划的目标是开发不同的材料，以满足通信中光学工程、农业和生物光子学的特定应用需求。更具体地说，我们将启动一个新的项目，在聚碳酸酯上使用接枝染料来实现一种可能使用塑料注射技术形成的聚合物。该材料将提供适用于全息数据存储的可擦除记录介质。这种光致变色系统将代表对HDS行业所描述的问题的答案。

Materials for application in Optical Engineering are still representing the main bottleneck stopping the development of technology. Efforts have to be made to develop new materials, study their fabrication and to characterize them according to the foreseen technology. My research group is studying different types of materials such as photopolymers, dye-dopes polymers, chalcogenides and photonic band gap crystals. Polymers materials are offering very elegant and cheap solutions to problems faced by the Optical Engineering Industries. Those materials can be used to make photonic components, biophotonics and agrophotonics sensors, etc. Chalcogenide films are still being considered as promising materials for numerous optical applications. We have developed expertises in Sol-gel fabrication and MetalOrganic Deposition of materials which can be bringing to an aligned crystalline structure. Photonic Band Gap made by use of nanosphere of polymers has been made but techniques and quality of those crystals need to be studied. The objective of the proposed research program is the development of different materials that will address the needs of specific applications in Optical Engineering, Agro and Biophotonics, in Communications. More specifically, we will start a new program using grafted dye on a polycarbonate to realize a polymer that might be formed using plastic injection techniques. This material will provide an erasable recording media suitable for holographic data storage. This photochromic system will represent an answer to problems described by HDS industry.
