An all-fiber dense wavelength-division multiplexer/demultiplexer using photoimprinted Bragg gratings

• Frédéric Bilodeau, D. C. Johnson, Steven Theriault, Brigitte Malo, J. Albert, K. O. Hill
• IEEE Photonics Technology Letters
• 1995

A wavelength multiplexing/demultiplexing device is fabricated and used to drop/insert a single wavelength channel from/into a multiple wavelength transmission link with 100 GHz channel-spacing at… (More)

Disentangling trophic relationships in a High Arctic tundra ecosystem through food web modeling.

• Pierre Legagneux, G. Gauthier, +9 authors Carolyn Krebs
• Ecology
• 2012

Determining the manner in which food webs will respond to environmental changes is difficult because the relative importance of top-down vs. bottom-up forces in controlling ecosystems is still… (More)

Comparison of fiber Bragg grating dispersion-compensators made with holographic and e-beam written phase masks

• S. J. Mihailov, Frédéric Bilodeau, +4 authors C. Shu
• IEEE Photonics Technology Letters
• 1999

Experimental results of time delay ripples in dispersion compensating fiber Bragg gratings fabricated with either holographic or electron-beam written 10-cm-long phase masks are presented. Deviations… (More)

Photosensitization of optical fiber and silica-on-silicon/silica waveguides.

• Frédéric Bilodeau, Brigitte Malo, +5 authors Mark H. Kawachi
• Optics letters
• 1993

Localized heating with a flame is shown to be a simple and effective method for substantially augmenting the photosensitivity of high-silica optical waveguides to (UV) light. The method increases the… (More)

High-return-loss narrowband all-fiber bandpass Bragg transmission filter

• Frédéric Bilodeau, K. O. Hill, Brigitte Malo, D. C. Johnson, J. Albert
• IEEE Photonics Technology Letters
• 1994

An all-fiber narrowband transmission filter (FWHM=0.25 nm) that is compact and exhibits high return loss (30 dB or better) is demonstrated using simultaneously written matched-pair, side-by-side… (More)

Highly Overlapping Winter Diet in Two Sympatric Lemming Species Revealed by DNA Metabarcoding

• Eeva M. Soininen, Gilles Gauthier, +11 authors Nigel Gilles Yoccoz
• PloS one
• 2015

Sympatric species are expected to minimize competition by partitioning resources, especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime example of a situation… (More)

Compact, low-loss, fused biconical taper couplers: overcoupled operation and antisymmetric supermode cutoff.

• Frédéric Bilodeau, K. O. Hill, D. C. Johnson, Stéphane Faucher
• Optics letters
• 1987

The automated manufacture and characterization of compact four-port highly overcoupled fused couplers is reported. During the pulling stage of the manufacturing process, the light power in such… (More)

High throughput solid phase parallel synthesis of macrocyclic peptidomimetics.

• Éric Marsault, Hamid R. Hoveyda, +27 authors Pierre Deslongchamps
• Advances in experimental medicine and biology
• 2009

Chirped in-fiber Bragg gratings for compensation of optical-fiber dispersion.

• K. O. Hill, Frédéric Bilodeau, +5 authors Kazuo Takiguchi
• Optics letters
• 1994

A linearly chirped in-fiber Bragg grating is reported that can compensate at 1549 nm for the dispersion [ approximately -19 ps/(nmkm)] of standard telecommunications optical fiber optimized for… (More)

The effect of snow cover on lemming population cycles in the Canadian High Arctic

• Frédéric Bilodeau, Gilles Gauthier, Dominique Berteaux
• Oecologia
• 2012

Rising temperatures and changes in the precipitation regime will have a strong impact on the quality of the snow cover in the Arctic. A snow cover of good quality protecting lemmings from cold… (More)
