Seimconductor Optoelectronic Devices

点击翻译按钮获取中文摘要

Professor Yariv and his co-workers are the innovators of the quantum well laser, a device which has tremendous potential for practical application in opto-electronic systems. NSF supported this early work and the research proposed here is a continuation of this effort. One major contribution will be both the theoretical and experimental study of these devices in order to achieve a major reduction in the threshold current. Because of materials problem associated with fabrication of these systems, Dr. Yariv has devoted considerable commitment, time, money and effort into materials technology to enhance this productive research.
