Quasi-solitons and stable superluminal opto-acoustic pulses in Brillouin scattering
Antoine F. J. Runge, Mikołaj K. Schmidt, Alexander S. Solntsev +2
We theoretically and numerically study the evolution of soliton-like waves supported by stimulated Brillouin scattering. First, the emergence and unusual behaviour of resonant soli…
Stimulated Brillouin Scattering in layered media: nanoscale enhancement of silicon
M. J. A. Smith, C. Wolff, C. G. Poulton +1
We report a theoretical study of Stimulated Brillouin Scattering (SBS) in general anisotropic media, incorporating the effects of both acoustic strain and local rotation in all cal…
Enhanced acousto-optic properties in layered media
M. J. A. Smith, C. Wolff, M. Lapine +2
We present a rigorous procedure for evaluating the photoelastic coefficients of a layered medium where the periodicity is smaller than the wavelengths of all optical and acoustic f…
Stimulated Brillouin scattering in metamaterials
M. J. A. Smith, B. T. Kuhlmey, C. Martijn de Sterke +3
We compute the SBS gain for a metamaterial comprising a cubic lattice of dielectric spheres suspended in a background dielectric material. Theoretical methods are presented to calc…
Metamaterial control of stimulated Brillouin scattering
M. J. A. Smith, B. T. Kuhlmey, C. Martijn de Sterke +3
Using full opto-acoustic numerical simulations, we demonstrate enhancement and suppression of the SBS gain in a metamaterial comprising a subwavelength cubic array of dielectric sp…
Brillouin resonance broadening due to structural variations in nanoscale waveguides
Christian Wolff, Raphael Van Laer, Michael J. Steel +2
We study the impact of structural variations (that is slowly varying geometry aberrations and internal strain fields) on the width and shape of the stimulated Brillouin scattering…
