This is a proposal to design, build, and evaluate photonic crystal nanophotonicwaveguide components and optical systems. The broad goals of this program are todevelop a practical nanophotonic technology, and to incorporate knowledge of theadvancements in photonics technology into the classroom. There has been a great deal ofresearch into photonic bandgap structures in the last few years. All of this work,however, has been done either as basic research on the optical properties of differentdielectric lattices or on single photonic components. My research at USC containsseveral programs in which the goals are to develop individual nanophotonic devices or toengineer a particular feature of one of these devices. This proposal is intended to buildon work ongoing in those programs and to integrate the results into an integrated opticalcommunication technology. Waveguides, of course, are important in their own right, butthey are also one of the key elements necessary to combine devices to form functionaloptical circuits. In doing this, care must be taken to minimize coupling and insertionlosses as well. There are several key questions to be investigated in this program. Whatis the origin of photonic crystal waveguide loss? How do we design efficient guiding inthin patterned films? What are the trade-offs between one-dimensional and two-dimensionalperiodic guiding structures? How do we go from single devices to an integrated optics technology using photonic crystals? What modeling algorithms can handle these structures efficiently, and are there system level modeling algorithms possible?

这是设计、构建和评估光子晶体纳米光子波导组件和光学系统的提案。该计划的总体目标是开发实用的纳米光子技术，并将光子技术进步的知识融入课堂。在过去的几年里，人们对光子带隙结构进行了大量的研究。然而，所有这些工作都是作为不同介电晶格的光学特性或单个光子组件的基础研究而完成的。我在南加州大学的研究包含几个项目，其目标是开发单独的纳米光子器件或设计其中一种器件的特定功能。该提案旨在以这些计划中正在进行的工作为基础，并将结果整合到集成光通信技术中。当然，波导本身很重要，但它们也是组合设备形成功能光学电路所需的关键元件之一。在此过程中，还必须注意尽量减少耦合和插入损耗。该计划有几个关键问题需要研究。光子晶体波导损耗的根源是什么？我们如何设计图案薄膜的有效引导？一维和二维周期引导结构之间的权衡是什么？我们如何从单一器件转向使用光子晶体的集成光学技术？哪些建模算法可以有效地处理这些结构，是否存在系统级建模算法？
