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.

0335082COLEMANTH纳米技术的目标是创建由于其纳米级尺寸而显示出新颖并显着改善特性的材料和设备。电子量子点（QD）和光子晶体（PHC）的技术收敛将为下一代纳米光源源提供一场革命，用于高带宽光学通信。但是，要实现这一目标，必须对电子和光子的系统进行密切设计，以使其各自的波形和状态密度之间的空间和光谱重叠。该提案旨在结合从量子点获得的三维电子限制中的积极进步，并与光子晶体实现的前所未有的光学限制，从而发展下一代高效的微型波动光学源。该提案有三个技术目标：（1）通过控制生长合成，展示了纳入工程量子点的光子源； （2）在二维（2D）光子晶体中展示了工程和电注入的光学纳米腔； （3）在2D光子晶体中将单个或几个耦合的量子点（S）整合在工程的光学纳米腔内。具有高效率光源具有高调制带宽和可控波长的开发将是通过超紧密的操作和/更进行的计算机处理的光学通信的革命性，用于光学通信的革命性进步。此外，拟议的研究将提供一个新的环境，以扩展对新型光学材料的纳米制作技术的理解。因此，拟议的研究将影响纳米技术，微腔物理学和下一代光子应用。此外，这项工作的指导哲学是本科生的实质性参与，针对代表性不足的群体的参与。 PI计划继续将中学和高中教师纳入研究计划，以训练和激发他们在新的科学领域，以使他们能够将其传递给学生。
