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

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.
