要求提供资金，以支持一项关于非对称多量子阱（AMQW）III-V族半导体二极管激光器的物理和应用的研究方案。 此外，还要求提供资金，以支持通过分析材料和器件的发光偏振度（DOP）来分析III-V材料和器件的研究。 对AMQW半导体二极管激光器的研究提供了对半导体二极管激光器操作的深入了解。 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的增益峰值，并且可以被设计为在宽的波长范围内工作。 因此，这些激光器可以有效地应用于计量。 预计该研究将导致对AMQW和非AMQW二极管激光器的知识和理解，并将在计量学中创造没有AMQW二极管激光器就不可行的应用。 申请人及其研究团队开发了通过分析发光DOP来分析III-V族材料。 发光的DOP与材料中的应变有关。 应变对于器件的可靠性很重要，特别是对于电信中使用的器件。 该研究计划使学生接触到广泛的实践技能，并需要广泛的知识基础和批判性思维。 因此，毕业生有技能和态度，以解决广泛的工作，并为社会作出贡献。

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.
