Journal ArticleDOI
Brillouin light scattering from surface acoustic waves in a subwavelength-diameter optical fibre
Jean-Charles Beugnot,Sylvie Lebrun,Gilles Pauliat,Hervé Maillotte,Vincent Laude,Thibaut Sylvestre +5 more
TL;DR: In a subwavelength-diameter optical fibre, the first experimental observation of Brillouin light scattering from surface acoustic waves is reported, which opens new opportunities for various sensing applications, not only in microwave photonics and nonlinear plasmonics.
Journal ArticleDOI
High Spatial and Spectral Resolution Long-Range Sensing Using Brillouin Echoes
TL;DR: In this article, a pre-activated acoustic field and an optical phase control over the interrogating pulse were used for high spatial and spectral resolution Brillouin sensing with enhanced signal to noise ratio.
Journal ArticleDOI
Complete experimental characterization of stimulated Brillouin scattering in photonic crystal fiber
Jean-Charles Beugnot,Thibaut Sylvestre,D. Alasia,Hervé Maillotte,Vincent Laude,Achille Monteville,Laurent Provino,Nicholas Traynor,S. Foaleng Mafang,Luc Thévenaz +9 more
TL;DR: This work provides 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 position-resolved mapping of the BrillouIn frequency shift.
Journal ArticleDOI
Distributed Brillouin sensing with sub-meter spatial resolution: modeling and processing
TL;DR: A general analytic solution for Brillouin distributed sensing in optical fibers with sub-meter spatial resolution is obtained by solving the acoustical-optical coupled wave equations by a perturbation method.
Journal ArticleDOI
Modeling light-sound interaction in nanoscale cavities and waveguides
Yan Pennec,Vincent Laude,Nikos Papanikolaou,Bahram Djafari-Rouhani,Mourad Oudich,Said El Jallal,Jean-Charles Beugnot,Jose M. Escalante,Alejandro Martínez +8 more
TL;DR: In this article, the authors describe the theoretical tools that allow the modeling of the interaction between photons and acous- tic phonons in nanoscale structures, namely cavities and waveguides, with special emphasis in phoxonic crystal structures.
