STRONG COUPLING EFFECTS AND POLARITON LASING WITH GaN AND ZnO - BASED NANOWIRES

本研究的目的是研究在室温下具有超低阈值功率的新型相干光源——极化激光器的物理、设计、制造和表征。该方法是用生长在硅和其他衬底上的氮化镓纳米线来设计激光器。将对具有光和电激励的单微腔和多微腔器件进行表征和分析。智力优势：智力优势是首次全面研究纳米线中的强耦合和玻色-爱因斯坦凝聚。电注入极化激子激光还没有实现，这个演示是革命性的。室温极化激子激光和玻色-爱因斯坦凝聚的演示也具有变革性，被认为是光电子学的里程碑。这些激光器将比目前正在探索的任何其他微腔激光器具有更低的阈值功率。更广泛的影响和人力资源开发：实现一种相干光源，其消耗的能量可能比当前激光器消耗的能量小三个数量级，这是绿色光子学的一个巨大飞跃，在电信、医疗和显示应用方面具有深远的影响。更广泛的影响是这项研究的跨学科性质，以及它对本科生和代表性不足的少数族裔和K-12的影响。教育和人力资源开发（EHRD）的主要目标是提供有效的计划来教育参与光子材料科学和技术研究和推广计划组成部分的学生，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.
