The goal of the proposed research programme is to develop information and communications network infrastructure capable of supporting new applications that push bandwidth and accessibility limits in the context of a low-carbon digital economy. Specifically, it is proposed to design and evaluate the performance of an energy efficient network infrastructure that features a unified control plane to integrate the Internet protocol into optical metro networks to provide flexible and intelligent bandwidth on demand for cloud computing; to develop fast and scalable single-chip transparent optical switches critical to the implementation; and, contribute to the sustainability of the technology through longer term research to transform new concepts in nanophotonic devices and integration from curiosities into ultra-low energy consumption photonic devices that approach thermodynamic limits. The expected results are: system architectures uniquely designed to deal with escalating information and communications technology network energy costs; single chip optical phased array switches and switch fabrics that may be expected to revolutionise photonic network thinking and ignite interest in commercialisation; novel phase-shift elements and coherent electro-optical frequency up-converters that will ensure the competitiveness of 'digital coherent optical transport of radio over fibre' for broadband wireless access and significantly advance the research agenda on 'coherent optical transmission everywhere', which uniquely challenges conventional modulation architectures. The outcomes will contribute to the success of Canada's strategy for a digital economy; tearing down barriers to the realisation of 'sustainable digital cities' vital to the world economy in the third millennium. Most important, the research will develop highly qualified and skilled personnel promoting effective knowledge transfer and helping to fill the employment needs of Canadian industry.

拟议研究计划的目标是开发能够支持在低碳数字经济背景下突破带宽和可访问性限制的新应用的信息和通信网络基础设施。具体而言，建议设计和评估具有统一控制平面的节能网络基础设施的性能，以将互联网协议集成到光城域网中，为云计算提供灵活和智能的带宽需求；开发快速、可扩展的单芯片透明光开关对实现至关重要；并且，通过长期研究，将纳米光子器件中的新概念转化为接近热力学极限的超低能耗光子器件，从而促进该技术的可持续性。预期结果是：系统架构设计独特，以应对不断升级的信息和通信技术网络能源成本；单芯片光学相控阵开关和开关结构有望彻底改变光子网络的思维方式，并引发对商业化的兴趣；新型相移元件和相干电光频率上转换器将确保宽带无线接入的“光纤上无线电数字相干光传输”的竞争力，并显著推进“无处不在的相干光传输”的研究议程，这是对传统调制架构的独特挑战。其结果将有助于加拿大数字经济战略的成功；消除实现“可持续数字城市”的障碍，这对第三个千年的世界经济至关重要。最重要的是，该研究将培养高素质和熟练的人才，促进有效的知识转移，帮助填补加拿大工业的就业需求。
