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

智能价值这一小型企业ERC协作机会将集成接入网络的灵活宽带发射器过渡到市场，将解决为数据中心和聚合网络等应用实现距离长达2公里的高带宽(100+Gb/S)、低功率、低成本波分复用(WDM)光通信链路的挑战。这些链路是下一代数据中心和超级计算应用所必需的，这些应用是中国电子研究中心S研究的重点。具体地说，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，这些系统驱动了链路的大部分成本、性能和功率需求。与传统解决方案相比，可调VCSEL的功率和成本降低了10倍，并支持数据中心内的高带宽链路，而目前的技术在经济上是不可行的。广泛影响该项目的更广泛的影响/商业潜力是大幅减少数据中心和超级计算机内光纤链路的成本能源需求。谷歌、微软和其他以数据为中心的大型公司在过去一年里一直在叫嚣着要推出这种类型的产品，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激光阵列解决方案需要的功率和成本是基于VCSEL的方法的10倍，在经济上是不可行的。另一方面，目前基于VCSEL的850 nm链路在没有耗电的TEC冷却器的情况下无法制成WDM源，因为它们缺乏精确的网格化波长控制，从而限制了整体链路速度。使用1550 nm可调谐的VCSEL既解决了栅格波长控制的问题，又允许使用低成本的单模光纤和为1550 nm WDM光纤链路开发的基础设施。在WDM系统中实现可调VCSEL将导致数据中心高速光纤链路的成本和能源需求降低到原来的1/10，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展。除了技术影响，这一合作项目将为中国学生提供真实世界商业产品开发过程的洞察力和体验。学员将在产品开发过程中进行测试并提供反馈，以增强他们的教育经验。VCSEL的增强能力将支持新的应用，并增强中国电信在其中的使命-S的使命是通过灵活的波长转换和光开关尽可能支持透明度，并支持网络中可动态重新配置的异质流量。

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.
