Phonons are quasi-particles relatively unexploited for application purposes, in comparison with electrons and photons. GaAs/AlAs heterostructures like superlattices have been established as a platform that allows engineering the propagation and confi

Stimulated Brillouin Scattering (SBS) is a coherent interaction process in which light is scattered from optically generated acoustic waves. It is a powerful tool for microwave and optical signal processing, distributed sensing and spectroscopy. Bril

International audience; While usually negligible in standard optical fibers, the group velocity dispersion of acoustic waves may in some cases play a significant role in the dynamics of stimulated Brillouin scattering (SBS) in propagation medias with

During the last decade, it is worth to mention the significant evolution of the spectral coverage of compact coherent laser sources towards the mid-infrared, in particular stimulated by spectroscopy and bio-photonic applications. The present thesis i
