Career: Photonic Crystal Waveguides and Device Integration

这是一个设计、构建和评估光子晶体纳米光子波导组件和光学系统的建议。该计划的主要目标是开发一种实用的纳米光子技术，并将光子技术的进步知识融入课堂。近年来，对光子带隙结构进行了大量的研究。然而，所有这些工作都是对不同介电晶格或单个光子组分的光学特性进行的基础研究。我在南加州大学的研究包括几个项目，其中的目标是开发单个纳米光子器件或设计其中一个器件的特定功能。本提案旨在构建这些项目中正在进行的工作，并将结果集成到集成光通信技术中。当然，波导本身就很重要，但它们也是组合器件以形成功能性光学电路所必需的关键元素之一。在此过程中，必须注意最小化耦合和插入损失。在这个项目中有几个关键问题需要研究。光子晶体波导损耗的来源是什么？我们如何设计有效的引导在薄的图案薄膜？一维和二维周期导向结构之间的权衡是什么？我们如何利用光子晶体从单一器件发展到集成光学技术？什么样的建模算法可以有效地处理这些结构，是否有可能的系统级建模算法？

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?
