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.

在通信网络上，对增加带宽的需求似乎是无限的，这是对硬件和软件工程师所面临的最大技术挑战。带宽需求的指标包括连接到Internet的设备数量以及数据中心内的总流量；两者都表现出指数增长。前者直接与所谓的The Internet（IoT）有关，而后者则呈现出不可避免的轨迹的路线图的鲜明现实，但是为此，未知的解决方案尚不清楚或尚未实施。 该提案将利用称为硅光子学（SIP）的强大技术来满足可扩展且具有成本效益的网络硬件的需求。以最基本的水平，SIP将电子与光学量子相结合，并具有显着的性能增长； SIP将在各个距离上革新数据传输。在提案中，我描述了一项关于SIP系统材料和设备的研究的创新计划。该计划是研究生工程师的强大训练工具。 我将探索通过硅波导中的离子植入设计的缺陷特征。这样的缺陷在整体探测器中找到了利用率（例如）。在2000nm左右的波长中，正在开发新的通信窗口，这一点尤其重要。随后，我将在2000nm上制造完整的SIP平台，并演示以> 25GB/s的操作。我将开发离子束技术，这表明有望选择性合成硅葡萄干在需要应变工程的应用中。使用硅微孔调制器，我将把以前的工作扩展到高度集成的WDM收发器上。我将探讨用于微区稳定和制作后修剪的方法，以大大减少相关的电力预算。我将使用硅微孔调制器来扩展我以前的色散补偿工作，以使用复合元素，例如双环或环辅助Mach-Zehnders，这些元件将提供链路分散调整。 我将追求子载波调制的概念，目的是实现与WDM结合使用的数据传输速率接近1TB/s的数据传输速率。 对加拿大人的切实福利将包括：a）对加拿大饮食行业的战略支持； b）HQP直接培训为重要的工业部门c）实现新的sip启用产品和服务。从广义上讲，这项工作将构成不断发展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，访问其环境信息，需要快速医疗诊断并利用消费电子产品。
