Phase sensitivity to axial strain of microstrustured optical silica fibers

International audienceWe compare, thanks to a Sagnac interferometer, the phase sensitivity to strain of different microstructured optical silica fibers (MSF) that we design and fabricate. Our results show that when a same elongation is applied to different MSF, the induced phase change is equal or lower than the one obtained for a standard fiber, showing no advantage on this parameter for sensing applications

Realizing optical amplifiers with micro-sphere: A 15 dB gain, 2 dB noise-figure, tiny amplifier

CLEO-Europe topic CJ " Fibre and Guided Wave Lasers and Amplifiers ", oral session: CJ6 " Fibre gratings and waveguide lasers " [CJ6-6-THU]International audience600 ppm Er3+ Al-doped silica micro-spheres are fabricated in order to realize optical amplifiers. We demonstrate that it is possible to obtain component showing 15 dB gain with 2 dB noise figure

Simultaneous measurement of anomalous group velocity dispersion and nonlinear coefficient in optical fibers using soliton effect compression

International audienceWe present a novel and simple method to measure both the value of the second-order dispersion coefficient and the nonlinear coefficient in optical fibers. This method is based on the higher-order soliton-effect pulse compression phenomenon and is valid for dispersion values greater than 0.5 ps/km/nm. A non-zero dispersion-shifted fiber, a standard single-mode fiber and a highly-dispersive highly-nonlinear fiber have been measured using this method

Une nouvelle méthode pour mesurer simultanément la dispersion et le coefficient non-linéaire de fibres optiques à dispersion positive

session 9 « Effets non linéaires » [S9O1]National audienceNous proposons une méthode qui permet de mesurer simultanément la dispersion d'ordre deux et le coefficient non-linéaire de fibres optiques en régime de dispersion anormale. La méthode est basée sur le phénomène de compression soliton d'ordre supérieur

Single mode holey fiber in GeGaSbS chalcogenide glass

oral session TuD "Continuum Generation and Photonic Crystal Fibers" [TuD3]International audienceWe present recent results on the fabrication of a single mode Holey Fiber in GeGaSbS chalcogenide glass using the “Stack&Draw” technique. We measure a Mode Field Diameter of 8,3 µm and we estimate at 200 W-1km-1 the γ value
