High performance computing systems and data centers dissipate a large amount of power, much of which is spent on data transmission. Optical technology is well poised to increase the efficiency of data transfer, however it brings along new types of energy losses associated with devices responsible for converting the information from the electrical domain, used for computation, to the optical domain, used for communication. This program will overcome this hurdle and will enable realization of efficient and compact electrical-to-optical converters. The program addresses topics related to optical communications, material science, computer modeling, nanotechnology, and electronics, and therefore represents a unique training ground for students at all levels. To engage a wider audience, the team members will prepare public lectures focused on discussing the science and technology used to realize the communication systems that modern society heavily relies on. The goal of this project is development of highly integrated, micrometer scale, lithium-niobate electro-optic modulators, that have the potential to enable large communication rates with minimal energy consumption. This will allow for efficient data transfer that could meet demanding requirements of future high performance computing systems. The proposed program will advance the state of the art of optoelectronic devices, will explore new device concepts and system architectures, will develop nanofabrication techniques suitable for realization of integrated modulators, and will develop new communication methods.

高性能计算系统和数据中心消耗大量电力，其中大部分用于数据传输。光学技术有望提高数据传输效率，但它带来了与负责将信息从用于计算的电域转换到用于通信的光域的设备相关的新型能量损失。该计划将克服这一障碍，并将实现高效、紧凑的电光转换器。该项目涉及与光通信、材料科学、计算机建模、纳米技术和电子学相关的主题，因此为各个级别的学生提供了一个独特的训练基地。为了吸引更广泛的受众，团队成员将准备公开讲座，重点讨论用于实现现代社会严重依赖的通信系统的科学和技术。该项目的目标是开发高度集成的微米级铌酸锂电光调制器，该调制器有潜力以最小的能耗实现高通信速率。这将实现高效的数据传输，满足未来高性能计算系统的苛刻要求。拟议的计划将推进光电器件的发展水平，探索新的器件概念和系统架构，开发适合实现集成调制器的纳米制造技术，并将开发新的通信方法。
