This CAREER project combines interdisciplinary research and education in optical and materials science focusing on photonic crystals. Research emphasis is on the fabrication of new functional materials--self-assembled photonic crystals (PCs), and exploration of their optical response with emphasis on metallo-dielectric photonic crystals (MDPCs) and polymeric PCs. New methods are proposed for the fabrication of three-dimensional MDPCs exploiting self-assembly of metallo-dielectric colloidal spheres. The primary goal of the research is to achieve a better understanding of light-matter interactions in photonic crystals, and to harness these effects to a variety of chal-lenging applications. In the linear regime, enhanced light transmission is predicted in MDPCs, compared to bulk metals, due to efficient coupling of the electromagnetic field into surface plas-mon-polaritons. While nonlinear properties of most bulk materials in the optical region are well understood, detailed studies of their manifestations in highly patterned structures are only begin-ning to emerge. Nonlinear PCs are predicted to exhibit enhanced nonlinear response, making them candidates for all-optical switching and frequency conversion applications. In addition to comparison with theoretical predictions and exploring new physical systems, these materials of-fer prospects for developing novel photonic devices. The approach includes three main objec-tives: 1) Adapting colloidal self-assembly and chemical synthesis techniques to fabricate novel three-dimensional PCs. 2) Detailed study of the optical properties - both linear and nonlinear of the composite materials. 3) Implementation of PCs in nonlinear optical devices, as a basis for fu-ture photonics technologies. %%% The project addresses fundamental materials science research issues having technological rele-vance. An important feature of the project is the strong emphasis on education, and the integra-tion of research and education. The education plan addresses four main objectives that mesh with the research, and are aimed at enhancing learning experiences in physics at the undergraduate and high school level. At the undergraduate level the aim is to expand avenues for learning, both by integrating key scientific journal publications in classroom teaching, and by offering undergraduate students working opportunities in the research group. At the graduate level the program ad-dresses the development of an Applied Physics program with emphasis in photonics. The research program offers graduate students opportunities for comprehensive research, to expand their skills as students and scientists while working towards their doctoral degree. Through mentoring of younger students, graduate students will also develop valuable leadership, teaching and collaborative skills. An educational outreach program includes a hands-on summer program in physics, aimed at able and eager high school students. The main emphasis of the educational program is on exposing students of all levels to research and scientific disciplines with a central goal to actively involve an increasing number of students in physical sciences.***

这个CAREER项目结合了光学和材料科学的跨学科研究和教育，重点是光子晶体。研究重点是新型功能材料——自组装光子晶体（PCs）的制备及其光学响应的探索，重点是金属介电光子晶体（MDPCs）和聚合物光子晶体。提出了利用金属介电胶体球自组装制备三维MDPCs的新方法。该研究的主要目标是更好地理解光子晶体中的光-物质相互作用，并利用这些效应进行各种具有挑战性的应用。在线性体系中，由于电磁场与表面等离子体非极化子的有效耦合，与大块金属相比，MDPCs中的光透射率预计会增强。虽然大多数块体材料在光学区域的非线性特性已经被很好地理解，但对它们在高图像化结构中的表现的详细研究才刚刚开始出现。非线性pc预计将表现出增强的非线性响应，使其成为全光开关和频率转换应用的候选者。除了与理论预测进行比较和探索新的物理系统外，这些材料还为开发新型光子器件提供了前景。该方法包括三个主要目标：1)采用胶体自组装和化学合成技术制备新型三维pc。2)详细研究复合材料的线性和非线性光学特性。3)在非线性光学器件中实现pc，为未来的光子学技术奠定基础。该项目涉及具有技术相关性的基础材料科学研究问题。该项目的一个重要特点是非常重视教育，并将研究与教育相结合。该教育计划涉及与研究相结合的四个主要目标，旨在提高本科和高中阶段的物理学习经验。在本科阶段，其目标是通过在课堂教学中整合重要的科学期刊出版物，以及为本科生提供在研究小组工作的机会，来扩大学习途径。在研究生阶段，该计划着重于光子学的应用物理计划的发展。该研究项目为研究生提供了全面研究的机会，在攻读博士学位的同时，扩大他们作为学生和科学家的技能。通过对年轻学生的指导，研究生也将培养有价值的领导、教学和协作技能。一个教育推广项目包括一个动手的暑期物理项目，目标是有能力和渴望的高中生。教育计划的主要重点是让各级学生接触研究和科学学科，其中心目标是使越来越多的学生积极参与物理科学
