ECS-0555278wei Li，威斯康星大学-普拉特维尔分校本科生获奖研究的目标是将相干控制的光子带隙应用于光电子器件设计，以获得一些具有光学调谐能力的器件，包括波长滤光器、脉冲形状控制器、开关、波长可调谐激光器等。首先，将优化纳米尺度的结构，即多量子阱，以在与受控激光相互作用时获得所需的最大光学性能增强。随后，这种新的材料结构将作为相干控制的光子带隙集成到光电子器件中。在器件级的建模和仿真中，将演示这种集成器件的操作和性能。作为最后一步，将考虑可能的制造问题/配方。该项目将极大地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。此外，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：这项研究不仅将有助于对纳米光子学的科学理解，而且还将对行业产品开发产生一些近期的工程影响。此外，通过这项研究，本科生的研究助理将得到深入的培训，如纳米技术，光子学和计算机辅助设计/工程等高级主题。它将加强本科工程课程，并直接惠及威斯康星大学普拉特维尔分校计划中的MEM/纳米技术课程。该项目还将有助于在该机构培养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.
