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.

AbstractObjective：该程序的目的是展示非二利氮化层级别激光器，以满足对整个未充分利用的近红外范围内设计的超快速紧凑光源的需求。该方法通过沿垂直于gan的M平面的无极化方向进行工程量子电荷 - 传输，消除了氮化物中内置极化场的不利影响。IntlectualFeel.Intlectual Forect：主要科学贡献是阐明内置极化场对NITRIDE近光LaSers and Nitride近光LASECTORS绩效的影响。该程序将启用一类新的多功能和超快速光电设备，这些设备将立即触发实际应用。新型的近红外设备将促进紧凑，负担得起的消费系统，并最终可能超过蓝色硝化激光器的商业成功。Broader的影响：该计划将增加来自印第安纳州中部经济不利的背景的7-12名学生对科学内容和光学方法的接触。基于询问的外展活动的全面进展旨在最大程度地发挥多个年龄段的影响。中学科学教师将制定和试点课程计划和演示，将红外辐射的概念纳入高中课程。将开发和实施为中学女孩的科学夏令营的动手活动。将特别注意评估这些活动对与电磁频谱无形区域有关的科学内容知识发展的影响。该综合教育计划将利用普渡大学的Nanohub.org上的现有基于Web的工具在全球研究界传播。
