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.

智力优势这一小型企业 ERC 合作机会将用于集成接入网络的敏捷宽带发射机推向市场，将解决实现距离长达 2 米的高带宽 (100+ Gb/s)、低功耗、低成本波分复用 (WDM) 光通信链路的挑战km 适用于数据中心和聚合网络等应用。这些链路是 CIAN ERC 研究重点的下一代数据中心和超级计算应用所必需的。具体来说，该项目将改进这些系统中的激光器，从而提高链路的成本、性能和功率要求，以满足当前的商业规格。与传统解决方案相比，可调谐 VCSEL 的功耗和成本降低了 10 倍，并可在数据中心内实现高带宽链路，而这在现有技术中在经济上是不可行的。 更广泛的影响 该项目更广泛的影响/商业潜力是光链路的成本和能源需求大幅降低数据中心和超级计算机内部。谷歌、微软等以数据为中心的大型公司去年一直在呼吁此类产品，以维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 10 倍的功率和 10 倍的光通量。基于 VCSEL 的方法成本高昂，并且在经济上不可行。另一方面，目前基于 850 nm VCSEL 的链路如果没有耗电的 TEC 冷却器就无法制成 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 VCSEL 既解决了网格波长控制问题，又允许使用低成本单模光纤和为 1550 nm WDM 光链路开发的基础设施。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。除了技术影响之外，此次合作还项目将为 CIAN 学生提供有关现实世界商业产品开发过程的见解和经验。学生将测试产品开发过程并提供反馈，从而增强他们的教育体验。 VCSEL 的增强功能将支持新应用并增强 CIAN 的使命，即通过灵活的波长转换和光开关尽可能支持透明度，并支持网络中动态可重新配置的异构流量。
