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…
Cascaded forward Brillouin scattering to all Stokes orders
Christian Wolff, Birgit Stiller, Benjamin. J. Eggleton +2
Inelastic scattering processes such as Brillouin scattering can often function in cascaded regimes and this is likely to occur in certain integrated opto-acoustic devices. We devel…
Stimulated Brillouin scattering enhancement in silicon inverse opal waveguides
M. J. A. Smith, C. Wolff, C. Martijn de Sterke +3
Silicon is an ideal material for on-chip applications, however its poor acoustic properties limit its performance for important optoacoustic applications, particularly for Stimulat…
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…
Power limits and a figure of merit for stimulated Brillouin scattering in the presence of third and fifth order loss
Christian Wolff, Philipp Gutsche, Michael J. Steel +2
We derive a set of design guidelines and a figure of merit to aid the engineering process of on-chip waveguides for strong Stimulated Brillouin Scattering (SBS). To this end, we ex…
Formal selection rules for Brillouin scattering in integrated waveguides and structured fibers
C. Wolff, M. J. Steel, C. G. Poulton
We derive formal selection rules for Stimulated Brillouin Scattering (SBS) in structured waveguides. Using a group-theoretical approach, we show how the waveguide symmetry determin…
