Mid-IR s-SNOM imaging of photo-induced refractive index variation in chalcogenide glass

L. Thomas, S. Eliet, J. Carcreff, Jean-Francois Lampin, Eugène Bychkov, David Le Coq, Pascal Masselin

We report the mid-IR s-SNOM surface characterization of a chalcogenide glass photo-inscribed by ultrashort laser pulses. Imaging allows to access to the morphology and the optical properties of the material at nanoscale, unravelling topographical and optical contrasts resulting from the laser…

Free induction decay signals stimulated by photomixing

Fuanki Bavedila, Guillaume Ducournau, Jean-Francois Lampin, Emilien Peytavit, Arnaud Cuisset, Gaël Mouret, Cyril Bray, Robin Bocquet, Francis Hindle

An optically driven photoconductor device is electrically pulsed to provide a powerful pulse around 206 GHz. The pulsed radiation polarizes the OCS gas which emits a free induction decay signal that is observed after the end of the pulse. This is the first step in the development of a photonic…

Nonlinear and Hysteretic Constitutive Models for Wave Propagation in Solid Media with Cracks and Contacts

Vladislav Aleshin, Steven Delrue, Olivier Bou Matar, Koen van den Abeele

This chapter is devoted to theoretical concepts and models for wave propagation, vibrations, or other elastic deformations in solids containing internal contacts (cracks, delaminations, etc.). A direct problem of solid mechanics is solved by building up a solution for elastic fields in materials…

Single-mode operation with no mode-hops of a 110m long Brillouin fiber laser with non-resonant pumping

Gwennaël Danion, Ludovic Frein, Denis Bacquet, Gregoire Pillet, Stéphanie Molin, Loic Morvan, Guillaume Ducournau, Marc Vallet, Pascal Szriftgiser, Mehdi Alouini

Stimulated Brillouin scattering (SBS) has received much attention for decades for its numerous applications in sensors, optical amplification or design of narrow-linewidth lasers. In particular, optical fibers present Brillouin gain with a narrow bandwidth of a few tens of MHz. This permits to…
