9612267 Houde-Walter The proposed research is a multidisciplinary effort involving University of Rochester and Stanford University, along with industrial collaborators from Eastman Kodak and Corning, to study the environments of rare-earth dopants and defects in optical glasses. The PIs propose to carry out spectroscopic analyses of impurities and defects in optical glasses to determine the nature of rare-earth environments. These analyses include optically detected magnetic resonance, nuclear magnetic resonance , x-ray absorption fine structure, electron spin resonance, and Raman spectroscopy. An understanding of the properties of these defects is critical to the production of glasses that exhibit higher gain and photo-induced index changes per induced absorption. These glasses, in turn, will make possible the development of new types of devices for optical telecommunications. %%% The proposed research is a multidisciplinary effort involving University of Rochester and Stanford University, along with industrial collaborators from Eastman Kodak and Corning, to study the environments of rare-earth dopants and defects in optical glasses.

Houde-Walter拟议的研究是一项多学科的努力，涉及罗切斯特大学和斯坦福大学，沿着来自伊士曼柯达和康宁的工业合作者，以研究光学玻璃中稀土掺杂剂和缺陷的环境。 研究所建议对光学玻璃中的杂质和缺陷进行光谱分析，以确定稀土环境的性质。 这些分析包括光学检测的磁共振、核磁共振、X射线吸收精细结构、电子自旋共振和拉曼光谱。 理解这些缺陷的性质对于生产具有更高增益和每诱导吸收光诱导折射率变化的玻璃至关重要。 反过来，这些玻璃将使开发新型光通信设备成为可能。 %这项拟议中的研究是一项多学科的努力，涉及罗切斯特大学和斯坦福大学，沿着来自伊士曼柯达和康宁的工业合作者，以研究光学玻璃中稀土掺杂剂和缺陷的环境。 研究所建议对光学玻璃中的杂质和缺陷进行光谱分析，以确定稀土环境的性质。 光学检测磁共振、核磁共振、X射线吸收精细结构、电子自旋共振和拉曼光谱将用于研究稀土掺杂玻璃中的缺陷。 对这些缺陷的理解将使材料研究人员能够生产出具有改进的光电性能的玻璃，这反过来又将使开发新型光通信器件成为可能。 ***
