本研究的目的是研究一类新的相干光源-偏振激元激光器-的物理，设计，制造和表征，可以在室温下具有超低阈值功率。 这种方法是设计在硅和其他衬底上生长GaN基纳米线的激光器。 单和多个微腔器件与光和电激发的特点和分析。智力优点：智力优点是第一次全面研究强耦合和玻色爱因斯坦凝聚在纳米线。 电注入的极化子激光还没有实现，这个演示是变革性的。 室温极化激元激光和玻色-爱因斯坦凝聚的演示也是变革性的，被认为是光电子学的里程碑。 这些激光器将有较低的阈值功率比任何其他微腔激光器目前正在探索。更广泛的影响和人力资源开发：实现一个相干光源，这将可能消耗的能量三个数量级小于目前的激光器所消耗的是一个量子飞跃的绿色光子与深远的影响，在电信，医疗和显示应用。 更广泛的影响是研究的跨学科性质及其本科生和代表性不足的少数民族和K-12外展。 教育和人力资源开发（EHRD）的主要目标是提供有效的计划，教育参与光子材料科学和技术研究和推广计划的学生，这被视为国家重要问题。

The objective of this research is to investigate the physics, design, fabrication and characterization of a new class of coherent light sources -- polariton lasers -- that can have ultra-low threshold powers at room temperature. The approach is to design the lasers with GaN-based nanowires grown on silicon and other substrates. Single and multiple microcavity devices with optical and electrical excitation will be characterized and analyzed.Intellectual Merit: The intellectual merit is the first comprehensive study of strong coupling and Bose-Einstein condensation in nanowires. Polariton lasing with electrical injection has not been achieved and this demonstration is transformative. Demonstration of room temperature polariton lasing and Bose-Einstein condensation are also transformative and are considered as milestones in optoelectronics. These lasers will have lower threshold powers than any other microcavity laser currently being explored.Broader Impacts and Human Resources Development: The realization of a coherent light source which will potentially consume energy three orders of magnitude smaller than that consumed by current lasers is a quantum leap for green photonics with far-reaching consequences in telecommunication, medical and display applications. The broader impacts are the interdisciplinary nature of the research and its undergraduate and underrepresented minorities and K-12 outreach. The principal goal in education and Human Resources Development (EHRD) is to provide effective programs to educate the students involved in the research and outreach program constituents on the science and technology of photonic materials, regarded as an issue of national importance.
