Advanced trends in nonlinear optics applied to distributed optical-fibre sensors

Dario Alasia

The distributed optical-fibre sensors based on the properties of Brillouin scattering is the central object of this thesis. In the past decade, optical fibres have gained a large interest as sensors: attractive solutions based on the non-linear stimulated ...

The effects of gamma-radiation on the properties of Brillouin scattering in standard Ge-doped optical fibres

Luc Thévenaz, Dario Alasia

We have experimentally studied the effects of gamma-radiation up to very high total doses on the physical properties of Brillouin scattering in standard commercially available optical fibres. A frequency variation of about 5 MHz for both Brillouin frequenc ...

Complete experimental characterization of stimulated Brillouin scattering in photonic crystal fiber

Luc Thévenaz, Dario Alasia

We provide a complete experimental characterization of stimulated Brillouin scattering in a 160 m long solid-core photonic crystal fiber, including threshold and spectrum measurements as well as positionresolved mapping of the Brillouin frequency shift. In ...

Mesure distribuée du gain d'un amplificateur paramétrique à fibre optique par rétro-diffusion Brillouin

Luc Thévenaz, Armand Vedadi-Comte, Dario Alasia

Nous avons réalisé, pour la première fois à notre connaissance, une mesure distribuée du gain paramétrique d’un amplificateur à fibre optique. La technique repose sur une analyse de la rétrodiffusion Brillouin dans le domaine temporel. Elle a permis de met ...
