0128975MoloneyThis award supports Jerome Moloney and students from the University of Arizona in a collaboration with Wulfhard Lange of the Department of Applied Physics at the University of Muenster, Germany. The aim of the international project is to make a systematic study of the spatio-temporal dynamics of technologically vertical-cavity surface-emitting lasers (VSCEL) devices. The effort will bring a leading experimental group in Germany together with the US group whose expertise is in modeling and simulation. The US group has established a unique capability to calculate from first principles the full many-body microscopic optical response of a great variety of semiconductor quantum well materials. These simulation tools will be extended to the study of VCSEL structures in order to investigate, among other phenomena, the role of oxidation layers and their geometry in controlling current spreading and diffractive spreading in very small and large aperture VCSELs. The international team makes a powerful joint theory and experimental program that will significantly impact a critical emerging technology sector. The work plan provides for extensive participation by graduate students in the international travel and research.

0128975 Moloneythis奖为亚利桑那大学的杰罗姆·莫洛尼（Jerome Moloney）和学生与德国芒斯特大学应用物理系的Wulfhard Lange合作。 国际项目的目的是对技术垂直腔体发射激光器（VSCEL）设备的时空动力学进行系统研究。 这项努力将使德国领先的实验小组与美国集团在建模和模拟方面的专业知识。 美国集团已经建立了独特的能力，可以从第一原理中计算出多种半导体量子井材料的全身微观光学响应。 这些仿真工具将扩展到对VCSEL结构的研究，以研究氧化层及其几何形状在控制电流扩散和衍射扩散中的作用。 国际团队制定了一个强大的联合理论和实验计划，将对关键的新兴技术部门产生重大影响。 该工作计划规定，研究生在国际旅行和研究中进行了广泛的参与。
