Composition-Structure-Property Relations in Inorganic Glasses

玻璃的一个重要应用是光信号传输，人们一直希望在更远的距离上传输越来越多的信息。这些要求要求对玻璃有新的思维方式，以及不同的玻璃化学物质施加的基本限制。在这项研究计划中，我们将结合先进的光学、结构和建模工作来研究这些问题，以确定玻璃中的基本化学键如何导致各种光学响应，并最终导致光学信号损失。我们的基本目标是在原始数据的基础上，对玻璃中由外加应力和温度引起的光与原子运动的相互作用产生新的理解。一旦实现，我们将能够设计和优化具有优异光学性能的新玻璃成分，以极大地改善光通信网络。我们计划的学员将接触到实验和计算材料科学方面的最先进能力，为他们未来在材料科学和工程这许多相关领域的工作做好准备。

An important application of glass is to optical signal transmission, and there is a constant desire to transmit more and more information over longer distances. These requirements demand new ways of thinking about glass and the fundamental limitations that different glass chemistries impose. In this research program we will study these issues by combining advanced optical, structural, and modeling work to determine how the basic chemical bonding in glass leads to various optical response, and ultimately, optical signal loss. Our fundamental goal is to develop a new understanding, based on original data, of the interaction of light with atomic motions in glass, as induced by both applied stresses and by temperature. Once achieved we will be in the position to design and optimize new glass compositions with superior optical properties, for vastly improved optical communication networks. Trainees in our program will be exposed to state-of-the-art capabilities in both experimental and computational materials science, preparing them for future work in this many related areas of materials science and engineering.
