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

这种小型企业ERC协作机会将用于集成接入网的敏捷宽带发射机推向市场，将解决实现高带宽（100+ Gb/s）、低功耗、低成本波分复用（WDM）光通信链路的挑战，该链路的距离可达2公里，适用于数据中心和聚合网络等应用。这些链接对于下一代数据中心和超级计算应用来说是必要的，而这些应用是CIAN ERC的重点。年代的研究。具体来说，该项目将改进这些系统中的激光器，这些系统驱动了链路的大部分成本，性能和功率要求，以满足当前的商业规范。与传统解决方案相比，可调谐vcsel的功耗和成本降低了10倍，并且可以在数据中心内实现高带宽链路，这在当前技术下是不可行的。更广泛的影响这个项目的更广泛的影响/商业潜力是数据中心和超级计算机内部光链路的持续能源需求的大幅减少。像bb0、微软和其他以数据为中心的大型公司在过去的一年中一直在要求这种类型的产品，以保持其数据中心设施的增长率。目前使用DFB激光器的WDM激光阵列解决方案需要10倍的功率和10倍的基于vcsel的方法的成本，并且在经济上不可行。另一方面，目前基于850纳米vcsel的链路，由于缺乏精确的、网格化的、波长控制，限制了整体链路速度，如果没有耗电的TEC散热器，就不能制成WDM源。使用1550 nm可调谐VCSEL解决了网格波长控制问题，并允许使用低成本单模光纤和1550 nm WDM光链路的开发基础设施。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，从而使下一代数据中心和超级计算机应用的计算能力进一步扩大。除了技术上的影响，这个合作项目将为西安大学的学生提供对现实世界商业产品开发过程的洞察力和经验。学生们将在产品开发过程中进行测试并提供反馈，以增强他们的教育体验。vcsel的增强功能将启用新的应用程序并增强其中的CIAN。通过灵活的波长转换和光交换机尽可能地支持透明度，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.
