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.

玻璃的一个重要应用是光信号传输，人们一直希望在更长的距离上传输越来越多的信息。 这些要求需要对玻璃进行新的思考，以及不同玻璃化学物质所带来的基本限制。在这项研究计划中，我们将通过结合先进的光学，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合如何导致各种光学响应，并最终导致光信号损失。我们的基本目标是发展一个新的理解，基于原始数据，光与玻璃中原子运动的相互作用，由施加的应力和温度引起。一旦实现，我们将能够设计和优化具有上级光学性能的新玻璃组合物，以大大改善光通信网络。我们计划的学员将接触到实验和计算材料科学的最先进能力，为材料科学和工程的许多相关领域的未来工作做好准备。
