Beaudette K, Baac HW, Madore WJ, Villiger M, Godbout N, Bouma BE, Boudoux C.
PMID: 25909013
Biomed Opt Express. 2015 Mar 16;6(4):1293-303. doi: 10.1364/BOE.6.001293. eCollection 2015 Apr 01.

Double-clad fiber (DCF) is herein used in conjunction with a double-clad fiber coupler (DCFC) to enable simultaneous and co-registered optical coherence tomography (OCT) and laser tissue coagulation. The DCF allows a single channel fiber-optic probe to be shared: i.e....

Surface plasmon resonance sensor interrogation with a double-clad fiber coupler and cladding modes excited by a tilted fiber Bragg grating.

Optics letters

Baiad MD, Gagné M, Madore WJ, De Montigny E, Godbout N, Boudoux C, Kashyap R.
PMID: 24322164
Opt Lett. 2013 Nov 15;38(22):4911-4. doi: 10.1364/OL.38.004911.

We present a novel optical fiber surface plasmon resonance (SPR) sensor scheme using reflected guided cladding modes captured by a double-clad fiber coupler and excited in a gold-coated fiber with a tilted Bragg grating. This new interrogation approach, based...

Delayed Endothelial Progenitor Cell Therapy Promotes Bone Defect Repair in a Clinically Relevant Rat Model.

Stem cells international

Bates BD, Godbout C, Ramnaraign DJ, Schemitsch EH, Nauth A.
PMID: 28523072
Stem Cells Int. 2017;2017:7923826. doi: 10.1155/2017/7923826. Epub 2017 Mar 30.

The repair of segmental bone defects remains a significant challenge for orthopaedic surgeons. Endothelial progenitor cells (EPCs) have successfully promoted the repair of acute defects in animal models; however, the ability of EPCs to induce the repair of chronic...

Characterization of femtosecond-laser pulse induced cell membrane nanosurgical attachment.

Biomedical optics express

Katchinskiy N, Godbout R, Elezzabi AY.
PMID: 27446703
Biomed Opt Express. 2016 Jun 22;7(7):2749-58. doi: 10.1364/BOE.7.002749. eCollection 2016 Jul 01.

This article provides insight into the mechanism of femtosecond laser nanosurgical attachment of cells. We have demonstrated that during the attachment of two retinoblastoma cells using sub-10 femtosecond laser pulses, with 800 nm central wavelength, the phospholipid molecules of...

Predictors of Dropout From Cognitive-Behavioral Group Treatment for Panic Disorder With Agoraphobia: An Exploratory Study.

Behavior modification

Bélanger C, Courchesne C, Leduc AG, Dugal C, El-Baalbaki G, Marchand A, Godbout N, Marcaurelle R, Perreault M.
PMID: 27385412

Panic disorder and agoraphobia are both characterized by avoidance behaviors, which are known correlates of treatment discontinuation. The aim of this exploratory study is to distinguish the profile of participants suffering from panic disorder with agoraphobia that complete treatment...

Nonlinear self-phase-modulation effects: a vectorial first-order perturbation approach.

Optics letters

Tzolov VP, Fontaine M, Godbout N, Lacroix S.
PMID: 19859219
Opt Lett. 1995 Mar 01;20(5):456-8. doi: 10.1364/ol.20.000456.

A full-vectorial integral expression is derived to compute the effective mode area of any Kerr-type nonlinearoptical waveguide working in a self-phase-modulation regime. In order to highlight the correction brought by the vectorial approach in a strong guidance situation, we...

Experimental loss-tolerant quantum coin flipping.

Nature communications

Berlín G, Brassard G, Bussières F, Godbout N, Slater JA, Tittel W.
PMID: 22127057
Nat Commun. 2011 Nov 29;2:561. doi: 10.1038/ncomms1572.

Coin flipping is a cryptographic primitive in which two distrustful parties wish to generate a random bit to choose between two alternatives. This task is impossible to realize when it relies solely on the asynchronous exchange of classical bits:...

Microstructured fiber source of photon pairs at widely separated wavelengths.

Optics letters

Slater JA, Corbeil JS, Virally S, Bussières F, Kudlinski A, Bouwmans G, Lacroix S, Godbout N, Tittel W.
PMID: 20160797
Opt Lett. 2010 Feb 15;35(4):499-501. doi: 10.1364/OL.35.000499.

We demonstrate a source of photon pairs with widely separated wavelengths, 810 and 1548 nm, generated through spontaneous four-wave mixing in a microstructured fiber. The second-order autocorrelation function g((2))(0) was measured to confirm the nonclassical nature of a heralded...

Donor-site morbidity of the inferior gluteal artery perforator flap for breast reconstruction in teenagers.

BACKGROUND/OBJECTIVE: Few options, apart from the buttock area, are available for autologous breast reconstruction in thin teenagers. The aim of the present study was to objectively evaluate and compare donor-site morbidity of the inferior gluteal artery perforator (IGAP) flap...

Spectrally resolved laser ranging with frequency combs.
