The seemingly insatiable demand for increased bandwidth on communication networks is presenting the greatest technological challenges ever made on hardware and software engineers alike. Indicators of bandwidth demand include the number of devices connected to the internet and the total traffic within data-centres; both exhibit exponential growth. The former relates directly to the so-called Internet-of-Things (IoT) while the latter presents the stark reality of a roadmap with an inevitable trajectory, but for which solutions for realization are not known, or have yet to be implemented. This proposal will address the need for network hardware that is scalable and cost-effective, utilizing the powerful technology known as Silicon Photonics (SiP). At its most fundamental level SiP integrates electronic with optical quanta with remarkable performance gains; SiP will revolutionize data transfer at all distances. In the proposal I describe an innovative program of research on materials and devices for SiP systems. The program is constructed as a strong training vehicle for graduate engineers. I will explore characteristics of defects engineered via ion implantation in silicon waveguides. Such defects find utilization (for example) in monolithic detectors. This is of particular importance at wavelengths around 2000nm where a new communication window is under development. I will subsequently fabricate a complete SiP platform for 2000nm and demonstrate an optical link operating at >25Gb/s. I will develop ion beam techniques which show promise for selective synthesis of germanium volumes in silicon for applications requiring strain engineering. Using silicon microring modulators I will expand my previous work on highly integrated WDM transceivers. I will explore methods for microring stabilization and post-fabrication trimming with the aim to dramatically reduce the associated power budget. I will expand on my previous work on dispersion compensation using silicon microring modulators to the use of compounded elements such as dual rings, or ring assisted Mach-Zehnders which will provide link-dispersion tuning. I will pursue the concept of sub-carrier modulation with the aim of realising data transfer rates approaching 1Tb/s for a single unit when combined with WDM. Tangible benefits to Canadians will include: a) strategic support for the Canadian SiP industry; b) direct training of HQP for a vital industrial sector c) realization of new SiP-enabled products and services. In a broad sense, this work will form part of the unfolding global information revolution which is experienced by Canadians who download information, take part in social networking, access information on their environment, require rapid medical diagnosis, and utilize consumer electronics.

对通信网络带宽增加的看似永无止境的需求给硬件和软件工程师带来了有史以来最大的技术挑战。带宽需求指标包括连接到互联网的设备数量和数据中心内的总流量；两者均呈现指数增长。前者与所谓的物联网（IoT）直接相关，而后者则呈现出具有不可避免轨迹的路线图的严酷现实，但实现解决方案尚不清楚，或尚未实施。 该提案将利用硅光子 (SiP) 等强大技术，满足对可扩展且经济高效的网络硬件的需求。在最基本的层面上，SiP 将电子与光学量子集成在一起，具有显着的性能提升； SiP 将彻底改变所有距离的数据传输。在提案中，我描述了一项有关 SiP 系统材料和器件的创新研究计划。该计划是为研究生工程师提供强大的培训工具。 我将探索通过硅波导中的离子注入设计的缺陷的特征。此类缺陷（例如）在单​​片探测器中得到了利用。这对于 2000nm 左右的波长尤其重要，新的通信窗口正在开发中。随后，我将制造一个完整的 2000nm SiP 平台，并演示以 >25Gb/s 运行的光学链路。我将开发离子束技术，该技术有望在需要应变工程的应用中选择性合成硅中的锗体积。使用硅微环调制器，我将扩展我之前在高度集成的 WDM 收发器方面的工作。我将探索微环稳定和制造后修整的方法，目的是大幅降低相关的功率预算。我将使用硅微环调制器扩展我之前关于色散补偿的工作，以使用复合元件，例如双环或环辅助马赫曾德尔，它们将提供链路色散调谐。 我将追求子载波调制的概念，目标是与 WDM 结合时实现单个单元接近 1Tb/s 的数据传输速率。 给加拿大人带来的切实好处包括： a) 对加拿大 SiP 行业的战略支持； b) 对重要工业部门的总部直接培训 c) 实现新的 SiP 产品和服务。从广义上讲，这项工作将成为正在展开的全球信息革命的一部分，加拿大人下载信息、参与社交网络、获取环境信息、需要快速医疗诊断和使用消费电子产品，正在经历这场革命。
