The objective of this research is to achieve direct excitation of surface plasmons (or surface plasma waves) from quantum dots. The approach to accomplishing this task starts with the high quality quantum dots grown using the Stranski-Krastanow self-assembly mechanism occurring during molecular beam epitaxy of the InAs/GaInAs/GaAs materials system in our laboratory. Combined with available e-beam lithography and imaging interferometric lithography, nanophotonic structures and devices investigating coupling will be grown, fabricated and characterized. Modeling using rigorous techniques evolved from coupled wave approaches will help in understanding of physical mechanisms such as dipole-dipole interactions coupling quantum dots and surface plasmons. Successfully achieving such a device structure may allow direct electrical excitation of surface plasmons and make possible several new devices replacing plasmon sensors based on attenuated total reflection. Furthermore, the approach taken by this program requires a level of understanding by the researcher of the interplay between materials, device, and electromagnetic properties that offers exceptional opportunities for the broad-based education of graduate students and postdoctoral associates. The University of New Mexico fulfills a key responsibility in the successful education of underrepresented groups at both the undergraduate and graduate levels. Our program strongly aligns with the outreach efforts of the National Nanotechnology Infrastructure network node recently established at the University of New Mexico that serves as a conduit for outreach to local public schools, but also has strong ties to local media that should aid in furthering public awareness and understanding of important developments in nanophotonics.

这项研究的目的是实现从量子点直接激发表面等离子激元(或表面等离子体波)。完成这一任务的方法是从我们实验室的InAs/GaInAs/GaAs材料系统的分子束外延过程中用STranski-Krastanow自组装机制生长的高质量量子点开始。结合现有的电子束光刻和成像干涉光刻，将生长、制造和表征研究耦合的纳米光子结构和器件。使用从耦合波方法发展而来的严格技术进行建模将有助于理解偶极-偶极相互作用、耦合量子点和表面等离子体等物理机制。这种器件结构的成功实现可能使表面等离子体的直接电激发成为可能，并使基于衰减全反射的等离子体传感器的几种新器件成为可能。此外，该项目所采取的方法需要研究人员对材料、设备和电磁特性之间的相互作用有一定程度的了解，这为研究生和博士后助理的广泛教育提供了特殊的机会。新墨西哥大学在成功地在本科生和研究生阶段对代表不足的群体进行教育方面履行了一项关键责任。我们的计划与新墨西哥大学最近建立的国家纳米技术基础设施网络节点的外联努力非常一致，该节点是联系当地公立学校的渠道，但也与当地媒体保持着牢固的联系，这应该有助于进一步提高公众对纳米光子学重要发展的认识和理解。
