Semiconductor Optoelectronic Devices

将开展半导体光电子学研究，重点是在光通信中的应用。将对半导体激光噪声进行分析，以确定半导体激光器光谱纯度的基本物理极限。这项工作将把之前关于噪声行为的自洽半经典理论的结果推广到全量子治疗，特别是量子井激光器。耦合半导体激光器中的失谐加载将从理论和实验两方面进行研究。高输出功率激光阵列将对光电子加工和器件的发展产生相当大的影响。包括制造技术在内的几个新想法可以克服目前在这一领域缺乏成功的一些问题。

Research in semiconductor-based optoelectronics will be conducted, with emphasis on applications to optical communication. Semiconducted laser noise will be analyzed to determine the basic physical limits to the spectral purity of semiconductor lasers. This work will extend the previous results on a self-consistent semiclassical theory of noise behavior to a full quantumtreatment, particularly quantum-well lasers. Detuned loading in coupledsemiconductor lasers will be pursued both theoretically and experimentally. High output power laser arrays which could have considerable impact on the development of optoelectronic processing and devices will be addressed. Several new ideas including fabrication techniques could overcome some of the current lack of success in this area.
