Funding is requested to support a program of research on the physics and applications of asymmetric multiple quantum well (AMQW) III-V semiconductor diode lasers. In addition, funding is requested to support research on analysis of III-V materials and devices by analysis of the degree of polarization (DOP) of luminescence from the materials and devices. Research on AMQW semiconductor diode lasers provides insight into the operation of semiconductor diode lasers. The market for semiconductor diode lasers is estimated at 3.5 billion dollars for 2010. Thus the suggested program of research has industrial and economic relevance. AMQW diode lasers have broad gain peaks and can be designed to operate over a broad range of wavelengths. These lasers thus can be applied effectively to metrology. It is expected that the research will result in knowledge and understanding of both AMQW and non-AMQW diode lasers and will create applications in metrology that would not be viable without AMQW diode lasers. Analysis of III-V materials by analysis of the DOP of luminescence was developed by the applicant and his research team. The DOP of luminescence is related to strain in materials. Strain is important in the reliability of devices, particularly for devices used in telecommunications. The research program exposes students to a wide range of hands-on skills, and requires a broad knowledge base and critical thinking. Graduates thus have the skills and attitude to tackle a wide range of jobs and to contribute to society.

请求资金支持非对称多量子阱 (AMQW) III-V 半导体二极管激光器的物理和应用研究计划。 此外，还请求资金支持通过分析材料和器件发光的偏振度（DOP）来分析 III-V 族材料和器件的研究。 对 AMQW 半导体二极管激光器的研究让我们深入了解半导体二极管激光器的工作原理。 2010 年半导体二极管激光器的市场估计为 35 亿美元。因此，建议的研究计划具有工业和经济相关性。 AMQW 二极管激光器具有宽增益峰值，可设计用于在宽波长范围内工作。 因此，这些激光器可以有效地应用于计量学。 预计这项研究将带来对 AMQW 和非 AMQW 二极管激光器的了解和理解，并将创造在没有 AMQW 二极管激光器的情况下无法实现的计量应用。 通过分析发光的DOP来分析III-V材料是由申请人及其研究团队开发的。 发光的 DOP 与材料中的应变有关。 应变对于设备的可靠性很重要，特别是对于电信中使用的设备。 该研究项目让学生接触广泛的实践技能，并需要广泛的知识基础和批判性思维。 因此，毕业生拥有处理各种工作并为社会做出贡献的技能和态度。
