U.S.-China Cooperative Research: Fabrication and Optical Studies of GaN Microcavities

9729582 Jiang and Lin该奖项支持美国堪萨斯州立大学物理系Jiang和J.Y. Lin以及北京大学物理系张北在氮化镓微腔的制造和光学研究方面的合作。氮化镓及其相关合金近年来因其在蓝色和紫外线波长活跃的光学器件以及能够在高温、高功率水平和恶劣环境下工作的电子器件中的应用而引起了相当大的兴趣。在拟议的合作研究期间，北京大学小组将制备微腔和激光腔，堪萨斯小组将进行皮秒时间分辨光致发光研究。本研究的主要目标是确定氮化物激光器中可能的激光机制，并研究和了解与未来氮化物光电器件（如微腔激光器和垂直腔表面发射激光器）相关的基本物理性质。

9729582 Jiang and Lin This award supports collaboration between H.X. Jiang and J.Y. Lin, Department of Physics, Kansas State University, and Bei Zhang, Department of Physics, Peking University, on fabrication and optical studies of gallium-nitride microcavities. Gallium nitride and its allied alloys have attracted considerable interest recently due to their applications for optical devices which are active in the blue and ultraviolet wavelengths, and electronic devices capable of operation at high temperature, high power levels, and harsh environments. During the period of the proposed cooperative research, microcavities and laser cavities will be prepared by the Peking University group and picosecond time-resolved photoluminescence studies will be carried out by the group at Kansas. The major goals of the research are to identify possible lasing mechanisms in nitride lasers and to investigate and understand the basic physical properties related to future nitride optoelectronic devices such as microcavity lasers and vertical-cavity surface-emitting lasers.
