Objective: This proposal brings together an international US-Ireland team of scientists at University of California Los Angeles (UCLA), the Cork Institute of Technology (CIT), and Queen's University Belfast (QUB) to explore a bottom-up approach to electrically-driven photonic crystal lasers (PCLs) using III-V nano-pillars (NP) grown on Si. This proposal presents a unique set of capabilities to remove deficiencies in NP characterization, making it possible to develop NP lasers to their potential. Intellectual merit: The NP-PCLs have been engineered to surpass the necessary 10 fJ/bit requirement for inter-chip communication by implementing a high-Q, small current aperture cavity with greater than 90% waveguide coupling efficiency. With this international collaboration a rapid development process is possible, where NP growth and device fabrication is performed at UCLA, pump-probe spectroscopy and emission dynamics is performed at TNI, and atom probe tomography and scanning Raman spectroscopy at QUB. The combined effort of the groups will allow researchers to quickly characterize material quality and gain, and evaluate device designs.Broader impacts: The cooperative interaction between the US and Ireland allows for a comprehensive project going much further than would be possible for any individual partner. The participating groups will exchange best practices in areas involving interdisciplinary research, student involvement in research, and community participation. These themes are supported by several efforts to incorporate the findings into nano-materials curricula, train graduate, undergraduate and high school students, and form a concerted effort aimed at increasing minority student participation both in the US and Ireland.

目标：该提案汇集了来自加州大学洛杉矶分校 (UCLA)、科克理工学院 (CIT) 和贝尔法斯特女王大学 (QUB) 的美国-爱尔兰国际科学家团队，探索使用生长在 Si 上的 III-V 纳米柱 (NP) 的电驱动光子晶体激光器 (PCL) 的自下而上方法。该提案提出了一套独特的功能，可以消除 NP 表征方面的缺陷，从而使开发 NP 激光器发挥其潜力成为可能。智力优势：NP-PCL 的设计超越了芯片间通信所需的 10 fJ/bit 要求，采用了高 Q 值、小电流孔径腔，波导耦合效率高于 90%。通过这种国际合作，快速开发过程成为可能，其中纳米粒子生长和器件制造在加州大学洛杉矶分校进行，泵浦探针光谱和发射动力学在 TNI 进行，原子探针断层扫描和扫描拉曼光谱在 QUB 进行。这些小组的共同努力将使研究人员能够快速表征材料质量和增益，并评估设备设计。更广泛的影响：美国和爱尔兰之间的合作互动使综合项目能够比任何单独的合作伙伴走得更远。参与小组将交流跨学科研究、学生参与研究和社区参与等领域的最佳实践。 这些主题得到了多项努力的支持，这些努力将这些发现纳入纳米材料课程，培训研究生、本科生和高中生，并形成一致努力，旨在提高美国和爱尔兰少数族裔学生的参与度。
