0335082ColemanThe goal of nanotechnology is to create materials and devices which exhibit novel and significantly improved properties due to their nanoscale size. The technology convergence of electronic quantum dots (QDs) and photonic crystals (PhCs) will enable a revolution for the next generation of nano-photonic sources for high bandwidth optical communication. However, to achieve this requires that both systems, electronic and photonic, must be intimately engineered to enable spatial and spectral overlap between their respective wavefunctions and density of states. This proposal seeks to combine aggressive advances in 3-dimensional electronic confinement obtained from quantum dots with the unprecedented optical confinement achieved from photonic crystals to develop the next generation of highly efficient microcavity optical sources. There are three technical objectives of this proposal: (1) demonstrate photonic sources incorporating engineered quantum dots through control of growth synthesis; (2) demonstrate engineered and electrically injected optical nano-cavities within a 2-dimensional (2D) photonic crystal; and (3) integrate a single or few coupled quantum dot(s) within an engineered optical nano-cavity in a 2D photonic crystal.The development of high efficiency optical sources with high modulation bandwidth and controllable wavelength will be a revolutionary advance for optical communications, by virtue of ultra-high operation performance and/or by enabling all optical signal processing and advanced computer processing. In addition, the proposed research will provide a new context to extend the understanding of nanofabrication techniques for novel optical materials. Therefore the proposed research will impact nanotechnology, microcavity physics, and the next generation of photonic applications. In addition, a guiding philosophy of the work is substantial involvement of undergraduates, targeted toward the participation of underrepresented groups. The PI plans to continue the incorporation of middle and high school teachers into the research programs to train and inspire them in new areas of science, to enable them to pass this on to their pupils.

纳米技术的目标是创造出因其纳米尺寸而表现出新颖和显著改进性能的材料和设备。电子量子点(QD)和光子晶体(PHCS)的技术融合将为用于高带宽光通信的下一代纳米光子源带来一场革命。然而，要实现这一点，必须对电子和光子两个系统进行密切的设计，以使它们各自的波函数和态密度之间能够在空间和光谱上重叠。这一提议寻求将量子点在三维电子限制方面取得的积极进展与光子晶体获得的前所未有的光学限制相结合，以开发下一代高效微腔光源。该方案有三个技术目标：(1)通过控制生长合成来展示包含工程量子点的光子源；(2)展示二维(2D)光子晶体中的工程化和电注入的光学纳米腔；(3)在2D光子晶体的工程光学纳米腔中集成单个或更少的耦合量子点(S)。开发具有高调制带宽和波长可控的高效光源将是光通信的革命性进步，因为它具有超高的操作性能和/或使全光信号处理和先进的计算机处理成为可能。此外，拟议的研究将为扩大对新型光学材料的纳米制造技术的理解提供新的背景。因此，拟议的研究将影响纳米技术、微腔物理和下一代光子应用。此外，这项工作的指导思想是本科生的大量参与，目标是代表不足的群体的参与。PI计划继续将初中和高中教师纳入研究计划，在新的科学领域对他们进行培训和激励，使他们能够将这一点传授给他们的学生。
