AbstractObjective: The objective of this program is to demonstrate a non-polar nitride cascade laser to fill the need for ultra-fast compact light sources tunable by design in the entire underutilized near-infrared range. The approach eliminates the adverse effects of built-in polarization fields in nitrides by engineering quantum charge-transport along the polarization-free direction perpendicular to the m-plane of GaN.Intellectual merit: The main scientific contribution is to elucidate the impact of built-in polarization fields on the performance of nitride near-infrared lasers and detectors. The program will enable a new class of versatile and ultra-fast optoelectronic devices that will immediately trigger practical applications. The novel near-infrared devices will facilitate compact, affordable consumer systems and could eventually surpass the commercial success of the blue nitride lasers.Broader impacts: The program will increase exposure of Grade 7-12 students from economically disadvantaged backgrounds in Central Indiana to the scientific content and method of photonics. A comprehensive progression of inquiry-based outreach activities was designed to maximize impact across multiple age groups. Secondary science teachers will develop and pilot lesson plans and demonstrations that incorporate concepts of infrared radiation into the high-school curriculum. Engaging hands-on activities for a science summer camp for middle-school girls will be developed and implemented. Special attention will be given to assessing the impact of these activities on the development of knowledge about the science content related to invisible regions of the electromagnetic spectrum. The integrated educational plan will leverage existing web-based tools on Purdue's nanoHUB.org for dissemination across the global research community.

摘要目的：该计划的目的是展示一种非极性氮化物级联激光器，以满足对超快紧凑型光源的需求，该光源可通过设计在整个未充分利用的近红外范围内进行调谐。该方法通过沿垂直于 GaN m 面的无极化方向设计量子电荷传输，消除了氮化物中内置极化场的不利影响。 智力优点：主要科学贡献是阐明内置极化场的影响。偏振场对氮化物近红外激光器和探测器性能的影响。该计划将实现新型多功能、超快光电器件，并立即引发实际应用。这种新颖的近红外设备将促进紧凑、价格实惠的消费系统的发展，并最终可能超越蓝色氮化物激光器的商业成功。 更广泛的影响：该计划将增加印第安纳州中部经济困难家庭的 7-12 年级学生接触科学技术的机会。光子学的内容和方法。全面开展基于调查的外展活动旨在最大限度地提高对多个年龄段的影响。中学科学教师将制定并试点课程计划和演示，将红外辐射的概念纳入高中课程。将制定并实施针对中学生的科学夏令营实践活动。将特别关注评估这些活动对电磁频谱不可见区域相关科学内容知识发展的影响。综合教育计划将利用普渡大学 nanoHUB.org 上现有的基于网络的工具在全球研究界传播。
