Research Objectives and Approaches: The objective of this research is to elucidate the science underlying the optical properties of nanowires, and to harness these properties for novel photonic devices. The approach is to develop the science needed for nanowire-based photodetectors, for filter arrays for multispectral and polarization imaging, and for plasmonic lasers. The photodetector and filters will be based upon the recent discovery by the Principal Investigator's group that vertical silicon nanowires can appear a wide variety of colors that depend on their radii. The lasers will consist of nanowires positioned in plasmonic waveguides.Intellectual merit: Due to their unique attributes, much interest has been paid over the past decade to semiconducting nanowires. It is somewhat surprising how little attention has been paid to the dramatic effects that waveguiding and resonance phenomena can have upon their optical properties. This work will reveal the science, and demonstrate that these phenomena can be used advantageously for nanowire-based photonics.Broader impacts: While the proposed program will investigate the science, it is entirely possible that the devices studied in this work will find their way, in some form, into commercial products. The work therefore could contribute to the United States photonics industry. The project also creates not only the science, but also the human infrastructure required for future advances. The Principal Investigator will provide training to a diverse range of undergraduate and graduate students, and will undertake a variety of outreach efforts in the local community.

研究目标和方法：这项研究的目的是阐明纳米线的光学特性的基础科学，并利用这些特性用于新型光子设备。该方法是开发基于纳米线的光电电视器所需的科学，用于多光谱和极化成像以及等离子激光器的过滤器阵列。光电探测器和过滤器将基于主要研究者小组最近发现，即垂直硅纳米线可以看起来依赖于它们的半径的多种颜色。激光将由位于等离子波导中的纳米线组成。智能优点：由于其独特的属性，在过去的十年中，人们对半导体的纳米线已经支付了很大的兴趣。令人惊讶的是，对波浪和共振现象对它们的光学特性所产生的戏剧性影响的关注很少。这项工作将揭示科学，并证明这些现象可以在基于纳米线的光子学上有利地使用。Boader的影响：虽然拟议的计划将研究科学，但在这项工作中研究的设备完全有可能以某种形式找到自己的方式。因此，这项工作可以为美国光子学业做出贡献。该项目不仅创造了科学，而且还创造了未来进步所需的人类基础设施。首席研究人员将为各种本科生和研究生提供培训，并将在当地社区进行各种外展工作。
