Optics has had a tremendous impact on our quality of life by providing innovations in the areas of communications, sensing, medicine, and manufacturing. For example, advances in optical communications technology have led to dramatic changes in our society by enabling the exchange of information, services, and finance at unprecedented data rates. As a second example, optical sensing is now regularly used to help ensure a safe, living environment: we can monitor water and air quality, detect hazardous materials or chemicals, and probe the integrity of our civil and transportation infrastructure (e.g., buildings, bridges, pipelines, and airplanes). This research program focuses on enhancing optical communications and sensing using innovative waveguide and fiber device and subsystem designs. We will address the need for (1) optical device technologies and subsystems that perform a variety of signal processing functions at data rates beyond 40 Gb/s (e.g., 160 Gb/s) in order for systems and networks to satisfy bandwidth demand from emerging services and (2) cheap, rugged, tunable, and all-fiber mid-IR lasers for portable (in-field) IR-based chemical sensors. The program endeavours to advance fundamental knowledge, and generate new ideas, concepts, and methods to create significant opportunities in optical communications and sensing. The impact of the research is significant given the role of the global telecommunications infrastructure in society and the importance of environmental sensing using chemical spectroscopic techniques. The program will provide excellent training for 3 PhD students who will develop theoretical and practical skills that are highly sought by industry. Graduates of the current program have found employment at Infinera Corp., Optiwave, and Defence Research and Development Canada.

光学通过在通信、传感、医学和制造领域提供创新，对我们的生活质量产生了巨大影响。例如，光通信技术的进步通过以前所未有的数据速率交换信息、服务和金融，给我们的社会带来了巨大的变化。作为第二个例子，光学传感现在经常用于帮助确保安全的生活环境：我们可以监测水和空气质量，检测危险材料或化学品，并探测我们的民用和交通基础设施的完整性（例如，建筑物、桥梁、管道和飞机）。 该研究计划的重点是使用创新的波导和光纤器件和子系统设计来增强光通信和传感。我们将解决以下需求：（1）以超过40 Gb/s的数据速率执行各种信号处理功能的光学器件技术和子系统（例如，160 Gb/s），以使系统和网络满足新兴服务的带宽需求，以及（2）用于便携式（现场）基于IR的化学传感器的廉价、坚固、可调谐和全光纤中IR激光器。该计划致力于推进基础知识，并产生新的想法，概念和方法，以创造光通信和传感的重大机会。考虑到全球电信基础设施在社会中的作用以及使用化学光谱技术进行环境传感的重要性，这项研究的影响是重大的。该计划将为3名博士生提供优秀的培训，他们将发展行业高度追求的理论和实践技能。目前该项目的毕业生已在英飞朗公司找到工作，Optiwave和加拿大国防研究与发展部。
