Development of Advanced Technologies Enabling Next-Generation Optical Communications System.

为了实现可持续的经济增长，加拿大政府意识到其公民必须以可承受的价格接入互联网，无论是通过无线还是有线连接。这只有通过支持容量大得多的通信基础设施才能实现，使传输链路每秒传输1万亿比特（或太比特）。理论上只有光纤技术可以处理这样的容量。然而，在下一代光通信系统中，由于传输容量的增加，信号质量受到了影响。我的博士提案采用多学科方法来解决这个问题，通过联合研究更有效地调制光量的方法，以及通过信息处理来纠正传输过程中发生的电气错误。我的研究目标是在这些方法的基础上开发适当的技术，以促进加拿大下一代通信基础设施的部署。

To achieve sustainable economic growth, the government of Canada realizes that its citizens must have access to the Internet at affordable rates, either through wireless or wireline connections. This will only be possible through the support of a communication infrastructure with a much greater capacity, enabling a thousand billion bits (or Terabits) to be transported over transmission links each second. Only optical fiber technology can theoretically handle such a capacity. However in next-generation optical communication systems, signal quality is impaired by the increased transmission capacity of so many extra bits per second. My PhD proposal takes a multidisciplinary approach to this problem by jointly investigating ways to modulate the amount of light more efficiently, and to electrically correct errors occurring during transmission through the processing of information. The goal of my research is to develop appropriate technology, based on these methods, to facilitate the deployment of Canada's next-generation communications infrastructure. The research I propose to undertake will enable more pervasive, efficient and secure networks than those available today through increasing system margins, and increasing their capacity. It will also stimulate enhanced applications related to the Internet, including online businesses, health services and distance learning, which continuously push bandwidth and accessibility limits. This research relates to the information, communication and technology (ICT) sector, a research and development (R&D) priority area identified by Canada's Science, Technology and Innovation System (STIC) and Canada's economic action plan. Finally, I hope to enhance Canada's profile as a leader in the new digital economy through developing innovative low-cost approaches to create substantially greater capacities across the entire telecommunication network.
