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.
