Research project

Optical glass amplifiers for high capacity networks


Data traffic carried by communication networks is exploding, driven by the coming era of artificial intelligence and internet-of-things. This interconnected world creates an accelerating demand for bandwidth that is fast outstripping the limits of currently available technologies. Next generation optical networks urgently need to multiply the transmission paths through optical fiber links. Optical amplifiers are at the heart of these high-speed systems, allowing information to flow through transparent networks for thousands of kilometers. We are recruiting for a new four-year research project on Optical glass amplifiers for high capacity networks. In this project, the team will do experimental demonstrations of optical fiber amplifier with unique performances enabled by material research and innovative designs, including optimization with machine learning.

Candidates will be responsible for the design and test of optical fiber amplifiers. The optical fibers will be fabricated in our laboratories equipped with a modified chemical vapor deposition system (MCVD) and two fiber drawing towers. The amplifiers will be tested using the most advanced optical communication transmission testbeds, with spatial division multiplexing and coherent modulation formats, also available in our facility. Interested international candidates should have a M.Sc. diploma in electrical engineering, physics engineering, physics or material sciences. Previous experience in photonics or optical communications is an asset. Canadian students with B.Sc. will also be considered. Note that there is no French requirements and thesis can be written and defended in English. Excellent written and oral communications skills in English is required and learning of French will be encouraged.

The candidate will work in a team of elite researchers at the Centre for Optics, Photonics and Lasers (COPL), a multidisciplinary research centre comprising nearly 200 researchers including students, post-doctoral fellows, research professionals and more than 21 faculty members. Team members are Prof. Sophie LaRochelle, holder of the Canada research chair (CRC Tier 1) in Advanced photonics technologies for communications, Prof. Younès Messaddeq, holder of the Canada excellence research chair (CERCP) in Photonics Innovation, and Prof. Leslie Rusch, holder of the Canada research chair (CRC Tier 1) in Communication systems enabling the cloud. You will work under the direct supervision and co-supervision of two of these professors who have a strong history of collaboration and research excellence. The varied background of the research team and the high quality of the laboratory provide an exceptional research and training environment for students and early career researchers.
