Our vision is to develop the disruptive component technologies and network concepts that will enhance our communications infrastructure 1000-fold to meet our 20-year needs, avert network grid-lock and reduce energy consumption.With continued steep growth in transmitted data volumes on all media, there is a widely-recognized and urgent need for more sophisticated photonics technologies in both the core and access networks to forestall a 'capacity crunch' in the medium term. Our Programme involves two world-class groups ideally positioned to satisfy this need and reinforce the traditional leadership of the UK in this area. All-optical technologies can also save considerably on the rapidly-rising energy consumption of communications systems (several % of global energy consumption, similar to air transport!), as well as substituting for travel, (e.g. Cisco's ultrawideband telepresence system has halved their large worldwide travel budget). This proposal is therefore focused on one of the most important challenges facing our modern society - an energy-efficient, ultra-high capacity ICT infrastructure able to connect people and businesses seamlessly everywhere. Traffic on the global communications infrastructure continues to increase 80% year-on-year, driven by rapidly expanding and increasingly-demanding applications: YouTube, MMS, iPlayer, new concepts such as cloud computing, tele-surgery, the introduction of the iPhone alone proved a severe drain on the capacity of major carriers. Bandwidth growth in the access network is starting to overwhelm the available capacity in the core. In the last 10 years, the number of broadband subscribers worldwide has grown 100-fold. We are now rapidly approaching the fundamental data carrying capacity of current optical technology; moreover, the energy required to support today's growing, power-hungry, ICT infrastructure is looking worryingly unsustainable. It is time to ask hard questions about some long-held assumptions.We propose a radical transformation of the physical infrastructure underpinning today's networks by developing devices capable of 1000-fold improvements in performance, starting with a critical re-examination of some of the most basic transmission building blocks - the optical fibres, amplification and regeneration, and nonlinear switching and distribution. Since the inception of optical telecommunications 40 years ago, the silica fibre has been its work-horse. However, as it nears its capacity limits, a radical rethink can reap dividends in non-linear threshold, transmission window breadth and loss through new materials and designs, leading to 1000-fold improvements. In addition, current power-hungry electronic switches are bottlenecks that photonics can alleviate. Although immensely challenging, the new technologies that we propose have the potential to lead to major advances and benefits in many other important areas - including security, the environment, manufacturing and healthcare. If we are successful in achieving our objectives, the Programme will surely establish the UK firmly as the world leader in optical communications and networking technologies for decades to come.

我们的愿景是开发颠覆性的组件技术和网络概念，将我们的通信基础设施增强 1000 倍，以满足我们 20 年的需求，避免网络堵塞并减少能源消耗。随着所有媒体上传输数据量的持续急剧增长众所周知，核心网络和接入网络迫切需要更先进的光子技术，以防止中期出现“容量紧缩”。我们的计划涉及两个世界级的集团，它们非常适合满足这一需求并加强英国在该领域的传统领导地位。全光技术还可以大大节省通信系统快速增长的能源消耗（占全球能源消耗的百分之几，类似于航空运输！），以及替代旅行（例如思科的超宽带远程呈现系统已将其大容量的能源消耗减少了一半）。全球旅行预算）。因此，该提案重点关注现代社会面临的最重要挑战之一——高效节能、超高容量的 ICT 基础设施，能够将世界各地的人们和企业无缝连接起来。全球通信基础设施上的流量继续同比增长 80%，这得益于快速扩展且要求日益提高的应用程序：YouTube、MMS、iPlayer、云计算、远程手术等新概念、iPhone 的推出事实证明，这严重消耗了主要航空公司的运力。接入网络的带宽增长开始超过核心网络的可用容量。过去 10 年里，全球宽带用户数量增长了 100 倍。我们现在正在迅速接近当前光学技术的基本数据承载能力；此外，支持当今不断增长、耗电的信息通信技术基础设施所需的能源看起来不可持续，令人担忧。现在是时候对一些长期存在的假设提出尖锐的问题了。我们建议通过开发能够将性能提高 1000 倍的设备来彻底改造支撑当今网络的物理基础设施，首先对一些最重要的设备进行严格的重新检查。基本传输构建模块 - 光纤、放大和再生以及非线性交换和分配。自 40 年前光通信诞生以来，石英光纤一直是其主力。然而，当它接近其容量极限时，彻底的重新思考可以通过新材料和设计在非线性阈值、传输窗口宽度和损耗方面获得红利，从而实现 1000 倍的改进。此外，当前高耗电的电子开关是光子学可以缓解的瓶颈。尽管具有巨大的挑战性，但我们提出的新技术有可能在许多其他重要领域（包括安全、环境、制造和医疗保健）带来重大进步和好处。如果我们成功实现我们的目标，该计划必将使英国在未来几十年内牢固地成为光通信和网络技术的世界领导者。
