OPTION 1: Small-Business ERC Collaborative Opportunity for the transitioning of agile broadband transmitter for integrated access networks to market

智能优势此小型企业ERC协作机会旨在将集成接入网络的灵活宽带发射机推向市场，从而解决为数据中心和聚合网络等应用实现高带宽（100 Gb/s以上）、低功耗、低成本波分复用（WDM）光通信链路的挑战，链路距离可达2 km。这些链接是必要的下一代数据中心和超级计算应用程序，是一个重点的CIAN ERC？具体来说，该项目将改进这些系统中的激光器，以满足当前的商业规格，这些激光器驱动了链路的大部分成本、性能和功率要求。与传统解决方案相比，可调谐VCSEL的功耗和成本降低了10倍，并实现了数据中心内的高带宽链路，而这在当前技术下在经济上是不可行的。更广泛的影响该项目更广泛的影响/商业潜力是大幅降低数据中心和超级计算机内光链路的成本和能源需求。谷歌、微软和其他以数据为中心的大型公司在过去一年一直在呼吁这种类型的产品，以保持其数据中心设施的增长速度。目前使用DFB激光器的WDM激光器阵列解决方案需要10倍的功率和10倍的成本，基于VCSEL的方法，并且在经济上不可行。另一方面，目前的850 nm VCSEL链路由于缺乏精确的网格化波长控制，无法在没有耗电的TEC冷却器的情况下成为WDM源，从而限制了整体链路速度。使用1550 nm可调谐VCSEL解决了网格波长控制的问题，并允许使用低成本单模光纤和开发的1550 nm WDM光链路基础设施。在WDM系统中实现可调谐VCSEL将使数据中心高速光链路的成本和能源需求降低10倍，从而进一步扩展下一代数据中心和超级计算机应用的计算能力。除了技术影响外，这项合作计划还将为CIAN学生提供真实的世界商业产品开发过程的视野和经验。学生们将测试和反馈到产品开发过程中，提高他们的教育经验。VCSEL的增强功能将使新的应用程序和增强CIAN在它？其使命是尽可能地利用灵活的波长转换和光交换机来支持透明性，并支持网络中动态可重构的异构流量。

Intellectual MeritThis Small-Business ERC Collaborative Opportunity transitioning agile broadbandtransmitter for integrated access networks to market will address the challenge of achieving highbandwidth (100+ Gb/s), low power, low cost wavelength division multiplexed (WDM) opticalcommunications links of distances up to 2 km for applications such as data centers andaggregation networks. These links are necessary for next generation data center andsupercomputing applications that are a focus of the CIAN ERC?s research.Specifically, this project will improve the lasers in these systems, which drive much ofthe cost, performance, and power requirements for the links, to meet current commercialspecifications. The tunable VCSELs offer a 10X reduction in power and cost over conventionalsolutions and enable high bandwidth links within data centers that not economically feasible withcurrent technologies.Broader ImpactsThe broader impact/commercial potential of this project is a drastic reduction in the costand energy requirements of optical links inside of data centers and supercomputers. Companiessuch as Google, Microsoft and other large data-centric companies have been clamoring for thistype of product in the last year to maintain the rate of growth in their data center facilities.Present WDM laser array solutions using DFB lasers require 10X the power and 10X the cost ofa VCSEL-based approach and are not economically feasible. Present 850-nm VCSEL-basedlinks, on the other hand, cannot be made into a WDM source without power-hungry TEC coolersdue to their lack of precise, gridded, wavelength control, limiting the overall link speed. Using a1550 nm tunable VCSEL solves both the problem of gridded wavelength control and allows theuse of low cost single mode fiber and the developed infrastructure for 1550 nm WDM opticallinks. The realization of tunable VCSELs in WDM systems will result in a 10X reduction inboth cost and energy requirements in high-speed optical links for data centers, enabling thefurther scaling of computational power for next generation data center and supercomputerapplications.Besides the technological impact, this collaboration program will offer CIAN studentsinsight and experience with the real world commercial product development process. Thestudents will be testing and giving feedback into the product development process, enhancingtheir educational experience. The enhanced capabilities of the VCSELs will enable newapplications and enhance CIAN in it?s mission of supporting transparency wherever possiblewith flexible wavelength conversion and optical switches, and supporting dynamicallyreconfigurable heterogeneous traffic in the network.
