The objective of this research project is to accomplish miniaturization, high-density integration and advanced packaging of photonic devices for large-bandwidth signal processing. The approach is to develop photonic devices by assembling silica nanowires on a silica aerogel substrate. Prof. Eric Mazur's research group has extensive expertise in the fabrication of silica nanowires and in nonlinear optics. A number of nanowire-based devices will be fabricated, including splitters, controllable fiber mirrors and optical logic gates. These devices will lay the groundwork for the miniaturization and integration of optical circuits. Intellectual MeritThe group's recently developed nanowire fabrication technique offers a new avenue for realizing small and highly integrated optical circuits. The first step toward reaching this goal is the development of the basic optical components that are the deliverables of this project. The approach is very different from existing microphotonic approaches and offers the opportunity of making major advances in the field. The proposed optical components will enable simple, all-optical logic operations at the microscale. Beyond these immediate goals, the proposed work will also contribute to the understanding of optical wave propagation at the nanoscale and permit advances in laser-induced breakdown spectroscopy and optical memory read-out. Broader ImpactThe proposed work will also contribute to the education and the training of future multidisciplinary scientists and engineers through research-based education of undergraduate and graduate students. Finally, using the group's well-established program integrating outreach and public education with research, this work will be broadly disseminated to the general public.

本研究计画之目标为实现大频宽讯号处理之光子元件之小型化、高密度积体化及先进封装。该方法是通过在二氧化硅气凝胶基底上组装二氧化硅纳米线来开发光子器件。Eric Mazur教授的研究小组在二氧化硅纳米线的制造和非线性光学方面拥有丰富的专业知识。将制造许多基于光纤的器件，包括分束器、可控光纤镜和光学逻辑门。这些器件将为光路的小型化和集成化奠定基础。该小组最近开发的纳米线制造技术为实现小型和高度集成的光学电路提供了新的途径。实现这一目标的第一步是开发基本的光学组件，这是该项目的可交付成果。该方法与现有的微光子方法非常不同，并提供了在该领域取得重大进展的机会。提出的光学元件将使简单的，全光学逻辑操作在微尺度。除了这些直接的目标，拟议的工作也将有助于理解光波在纳米尺度上的传播，并允许在激光诱导击穿光谱和光学存储器读出的进步。更广泛的影响拟议的工作也将有助于教育和培训未来的多学科科学家和工程师通过研究为基础的教育的本科生和研究生。最后，利用该小组完善的方案，将外联和公众教育与研究相结合，这项工作将广泛传播给公众。
