    Flexible trans-jacket inscription of fiber Bragg gratings for directional distributed sensing
    (2019-08-29) Morency, Steeve; Fortier, Richard; Messaddeq, Younès; Bernier, Martin; Trépanier, François; Boilard, Tommy
    An array of 18 FBGs spectrally distributed over 70 nm was written in a polyimide-coated fiber, with a single uniform phase-mask, by applying strain on the fiber prior to exposition. This flexible method will be used to develop directional sensor for distributed sensing based on a hybrid glasspolymer multicore fiber.

    Analysis of inter-core cross-gain modulation in cladding pumped multi-core fiber amplifiers
    (IEEE Xplore, 2018-11-15) Essiambre, René-Jean.; Chen, Haoshuo; Matte-Breton, Charles; Fontaine, Nicolas K.; LaRochelle, Sophie; Ryf, Roland; Messaddeq, Younès
    We numerically investigate pump-induced gain variations in eight-core fi ber amplifi ers. We compare two fi bers with different erbium profi les by varying input power from -25 dBm to 0 dBm in one or four cores. Inter-core cross-gain modulation is < 0.6 dB.
