Project objective: The objective of this project is to conduct theoretical and experimental research on the dispersion properties of nanostructured resonance elements. Fundamentally new types of dispersive devices using leaky-mode resonance effects in subwavelength photonic lattices will be designed, fabricated, and tested. Intellectual merit: This project charts new directions in photonic device technology based on nanostructured subwavelength elements. The proposed devices are unexploited in slow-light engineering. This project will define their applicability. Computations show that leaky-mode resonance devices compare favorably with leading concepts in the field. Although based on totally different fundamentals, in structure and device density, the proposed concept is similar to photonic-crystal based micro-resonator chips whose fabrication is particularly challenging. It appears that the proposed leaky-mode resonance delay lines can be fabricated more directly. Additionally, the elements show flat transmission spectra across useful bands. Detailed comparison requires fabrication and testing of prototype devices. As very little is currently known about these effects in the context of slow light, this project constitutes basic research.Broader impact: If the research verifies the practicality of these concepts, this work can have a major impact in promoting new device technology. Very compact optical delay lines, signal buffers in all-optical communication systems, and light-storage elements would become feasible. Moreover, this project is aligned with a broad plan to develop research and education in photonic nanostructures at the University of Texas at Arlington. It will strengthen research in photonic crystals and integrated photonic circuits and support efforts in building nanofabrication methods and infrastructure. With the principal investigator?s recent appointment to the Texas Instruments Distinguished University Chair in Nanoelectronics, major funding for equipment and facilities was provided. This project, which seeks mainly student salary support, would thus enhance the use of new, modern facilities. Therefore, the proposed project provides excellent analytical and experimental experience for both graduate and undergraduate students. There is special focus on recruiting female students as well as students belonging to populations that are underrepresented in science and engineering and converting them into new graduate students. In addition, the principal investigator is Chief Technical Officer of Resonant Sensors Incorporated, a start-up company developing new sensor technology. As part of his duties under the Texas Instruments Chair, he will teach a yearly course on entrepreneurship and business, open to all undergraduate and graduate students, to stimulate innovation and technology transfer. The results of this research will be widely disseminated in journals and conferences. As there is currently a heavy worldwide emphasis on the study of periodic layers and lattices, new publications and results, illustrating the interesting effects and applications realized in the leaky-mode regime, might stimulate additional research and technological progress.

项目目标：本计画的目的是对奈米结构共振元件的色散特性进行理论与实验研究。 利用亚波长光子晶格中的漏模共振效应，设计、制造和测试新型色散器件。智力价值：该项目绘制了基于纳米结构亚波长元件的光子器件技术的新方向。 所提出的设备在慢光工程中尚未开发。 本项目将确定其适用性。 计算表明，漏模谐振装置相比，在该领域的领先概念。 虽然基于完全不同的基本原理，在结构和器件密度，所提出的概念是类似的光子晶体为基础的微谐振器芯片的制造是特别具有挑战性的。 看来，建议的漏模谐振延迟线可以更直接地制作。 此外，元件在有用的频带上显示出平坦的透射光谱。 详细的比较需要制造和测试原型设备。 由于目前对慢光背景下的这些效应知之甚少，因此该项目构成基础研究。更广泛的影响：如果研究验证了这些概念的实用性，这项工作将对推动新设备技术产生重大影响。 非常紧凑的光延迟线、全光通信系统中的信号缓冲器和光存储元件将变得可行。 此外，该项目与德克萨斯大学阿灵顿分校的光子纳米结构研究和教育的广泛计划保持一致。 它将加强光子晶体和集成光子电路的研究，并支持建立纳米制造方法和基础设施的努力。 与首席调查员？最近被任命为德州仪器杰出大学纳米电子学教授，提供了设备和设施的主要资金。 这一项目主要寻求学生工资支持，因此将加强对新的现代化设施的利用。 因此，该项目为研究生和本科生提供了优秀的分析和实验经验。 特别注重招收女生以及理工科人数不足的学生，并将她们转变为新的研究生。 此外，首席研究员是Resonant Sensors Incorporated的首席技术官，Resonant Sensors Incorporated是一家开发新传感器技术的初创公司。 作为德州仪器主席职责的一部分，他将教授一门面向所有本科生和研究生的创业和商业年度课程，以刺激创新和技术转让。 这项研究的结果将在期刊和会议上广泛传播。 由于目前全世界都非常重视对周期层和晶格的研究，新的出版物和结果，说明了在漏模制度中实现的有趣效应和应用，可能会刺激更多的研究和技术进步。
