This PFI: AIR Technology Translation project focuses on translating a new low power, high bandwidth, holographic optical switch that will enable new architectures, improve data flow and increase energy efficiency in data centers. This new holographic switch is important because today's data centers consume 5% of the United States' electrical production and their power requirements are increasing exponentially as major companies such as Google, Facebook, and Amazon construct multi-acre data centers to satisfy consumer demand. The worldwide Internet traffic is forecasted to continue its rapid growth; doubling every 18 months due to new applications such as the Internet of Things. Unless a disruptive technology can be implemented, data centers' energy consumption will continue to grow at an exponential rate. The proposed holographic optical switch will enable new data center architectures that can dramatically reduce energy consumption while improving performance. The project will result in a prototype holographic optical switch and characterization of its performance in data center applications. This holographic switch has the following unique features: very low electrical power consumption, support for data rates to at least 1 Terrabit / second, and a flexible design that can provide a large number of input and output ports. These features provide advantages in term of energy efficiency, scalability, throughput, and data center architecture flexibility when compared to the existing electrical top-of-the-rack switches in the market space.This project addresses the following technology gaps as it translates from research discovery toward commercial applications. Commercial hybrid switching technology suffers from limited port count (~300 ports), long configuration time (10s of milliseconds) and high cost ($300/port). The proposal implements a switch based on integrating a novel holographic technique with a piston MOEMS (micro opto electro mechanical system) system. Our proposed system will overcome the limitations of the incumbent technology with the holographic switch which will provide high port count (10,000 ports), microsecond switching times (two orders of magnitude improvement), dramatically reduced cost per port ($10/port), enabling a 6× reduction in data center power consumption. The graduate students involved in this project will receive entrepreneurship training through seminars and lectures based upon the "Lean Startup" methodology described in "The Startup Owner's Manual" by Steven Blank. The students will also have direct interactions with industry through the CIAN ERC's Industrial Advisory Board.The project combines the holographic switching technology developed at U. Arizona with the Si-based piston MOEMS technology developed at UC Berkeley. TIPD, LLC will guide the commercialization aspects of this technology translation effort from research discovery toward commercial reality.

该PFI：AIR技术转换项目的重点是转换一种新的低功耗、高带宽、全息光学开关，该开关将支持新的架构，改善数据流并提高数据中心的能源效率。 这种新的全息开关非常重要，因为今天的数据中心消耗了美国5%的电力生产，并且随着谷歌，Facebook和亚马逊等大公司建造多英亩的数据中心以满足消费者需求，其电力需求呈指数级增长。预计全球互联网流量将继续快速增长;由于物联网等新应用，每18个月翻一番。 除非能够实施颠覆性技术，否则数据中心的能源消耗将继续以指数速度增长。提出的全息光开关将实现新的数据中心架构，可以大大降低能耗，同时提高性能。 该项目将产生一个原型全息光开关及其在数据中心应用中的性能表征。这种全息交换机具有以下独特的功能：非常低的电力消耗，支持至少1 Terrabit /秒的数据速率，以及灵活的设计，可以提供大量的输入和输出端口。 与市场上现有的架顶式电气交换机相比，这些功能在能源效率、可扩展性、吞吐量和数据中心架构灵活性方面具有优势。该项目解决了从研究发现到商业应用的以下技术差距。 商用混合交换技术的缺点是端口数量有限（约300个端口）、配置时间长（10毫秒）和成本高（300美元/端口）。该方案实现了一种基于集成一种新的全息技术与活塞MOEMS（微光机电系统）系统的开关。 我们提出的系统将利用全息交换机克服现有技术的局限性，提供高端口数（10，000个端口），微秒级切换时间（两个数量级的改进），大大降低每个端口的成本（10美元/端口），使数据中心功耗降低6倍。参与该项目的研究生将根据史蒂文·布兰克（Steven Blank）的《初创企业所有者手册》中描述的“精益初创”方法论，通过研讨会和讲座接受创业培训。 学生们还将通过CIAN ERC的工业咨询委员会与工业界直接互动。亚利桑那州与硅基活塞MOEMS技术开发的加州大学伯克利分校。TIPD，LLC将指导这项技术转化工作的商业化方面，从研究发现到商业现实。
