Research axes

Fiber-Optics and Guided-Wave Optics

The Fiber-optics and Guided-Wave Optics axis is concerned with the development of a new generation of functional optical components based on light confinement inside a guide, either cylindrical (fiber) or planar (integrated optics). This axis brings together 15 researchers from 5 universities and 1 CEGEP, in partnership with an applied research centre (INO). Their work provides solid support to the other axes that require custom-designed active and passive fibers and components for a variety of applications. The optical fiber fabrication facilities at Université Laval and the expertise of Professor Messaddeq’s Canada Excellence Research Chair are definite assets to this axis consisting of themes that cover all major guided-wave optics technologies.

These themes are focused on innovation in specialty optical fibers, fiber components and waveguides for applications in information technology and biophotonics.
