Fiber-optics and guided-wave optics

Head of Research: Nicolas Godbout

The Fiberoptics 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 13 researchers belonging to 5 universities and 1 college (Cégep) in partnership with 1 applied research center (INO). The work performed 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.

Theme 1 – Specialty optical fiber fabrication
Keywords: Silica, fluoride glass, chalcogenide, phosphate, germinate and polymer fibers. Single mode, multimode, multi-core, double-clad optical fibers. Micro-structured, Bragg, hollow core fibers. Fibers for the visible spectrum, for the near and far infrared, and for the Terahertz band. Highly-non-linear fibers.

Researchers in this theme: Messaddeq, Younès ; Godbout, Nicolas ; Kashyap, Raman ; LaRochelle, Sophie ; Olivier, Michel ; Rochette, Martin ; Skorobogatiy, Maksim ; Vallée, Réal
Theme 2 – Fiber-based components
Keywords: Fused couplers. Bragg gratings. Doped-fiber amplifiers. Supercontinuum. All-fiber filters : narrow band, tunable, gain flattening, multi-channel, etc. Fiber-tipped micro-probes. Femtosecond laser-photo-inscribed components. Power separators. Wavelength and mode multiplexing. Single-mode, multimode and double-clad components. Coherent demodulators. Interferometers. Quantum and non-linear components.
