李伟，美国威斯康辛大学- plattevilleintellectual Merit：本次本科院校研究奖的目的是将相干控制光子带隙应用于光电子器件设计，以获得一些具有光调谐能力的器件，包括波长滤波器，脉冲形状控制器，开关，波长可调谐激光器等。方法将包括理论研究和材料/器件建模和仿真。首先，将优化纳米级结构，即多量子阱，以在与受控激光束相互作用时获得最大期望的光学性能增强。随后，这种新材料结构将作为相干控制的光子带隙集成到光电器件中。在器件级的建模和仿真中，将展示这种集成器件的工作原理和性能。作为最后一步，可能的制作问题/食谱将被考虑。该项目将大大提高对各种半导体实现中相干控制量子干涉效应的基本物理理解。这些有趣的现象将创造性地应用于光电器件设计的工程应用中。更广泛的影响：该研究不仅有助于对纳米光子学的科学理解，而且对工业产品开发具有一定的近期工程影响。此外，通过这项研究，本科生研究助理将在纳米技术、光子学和计算机辅助设计/工程等高级课题上得到深入的培训。它将加强本科工程课程，并直接受益于威斯康星大学普拉特维尔分校计划中的MEM/纳米技术项目。该项目还将有助于在该机构培育一个令人兴奋的研究环境。

ECS-0555278Wei Li, University of Wisconsin-PlattevilleIntellectual Merit: The objective of this Research in Undergraduate Institutions award is to apply the coherently controlled photonic band gap to the optoelectronic device design in order to obtain some devices with optically tuned capability, which includes wavelength filter, pulse shape controller, switch, wavelength tunable laser, etc. The methodology will consist of the theoretical investigation and material/device modeling and simulation. First, the nanoscale structure, namely multi-quantum-well, will be optimized to obtain the maximum desired optical property enhancement while interacting with a controlled laser beam. Subsequently, this new material structure will be integrated into the optoelectronic device as a coherently controlled photonic band gap. In the device-level modeling and simulation, the operations and performances of this kind of integrated device will be demonstrated. As a final step, the possible fabrication issues/recipes will be considered. The project will greatly enhance the basic physics understanding of coherently controlled quantum interference effects in various semiconductor realizations. Furthermore these interesting phenomena will be creatively applied to the engineering applications in the optoelectronic device design. Broader Impacts: The research will not only contribute to scientific understanding on nanophotonics, but also have some near-term engineering impacts on the industry product development. In addition, through this research the undergraduate research assistants will get in-depth training on advanced topics such as nanotechnology, photonics and computer aided design/engineering. It will enhance the undergraduate engineering curriculum and benefit the planned MEM/Nanotechnology program directly at University of Wisconsin-Platteville. The project will also help nurture an exciting research environment in the institution.
