Stimulated Brillouin Scattering in InGaP-on-Insulator Waveguides
Yuyang Xue, Lisa-Sophie Haerteis, Ryan L. Russell +8
Stimulated Brillouin Scattering (SBS) is a nonlinear interaction between optical and acoustic waves in solids. First regarded as a parasitic process in optical fibers, it has gathe…
Suspended Z-cut lithium niobate waveguides for stimulated Brillouin scattering
Lisa-Sophie Haerteis, Yan Gao, Aditya Dubey +8
On-chip stimulated Brillouin scattering (SBS) has recently been demonstrated in thin-film lithium niobate (TFLN), an emerging material platform for integrated photonics offering la…
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…
Anti-resonant reflecting acoustic rib waveguides for strong opto-acoustic interaction
Thomas Dinter, Mikołaj K. Schmidt, Michael J. Steel
Few known material systems can simultaneously guide optical and elastic fields through total internal reflection. This natural limit has restricted the realization of strong optoac…
Noise and Pulse Dynamics in Backward Stimulated Brillouin Scattering
Oscar A. Nieves, Matthew D. Arnold, M. J. Steel +2
We theoretically and numerically study the effects of thermal noise on pulses in backwards Stimulated Brillouin Scattering (SBS). Using a combination of stochastic calculus and num…
Digital Waveguide Adiabatic Passage Part 1: Theory
Jesse A. Vaitkus, M. J. Steel, Andrew D. Greentree
Spatial adiabatic passage represents a new way to design integrated photonic devices. In conventional adiabatic passage designs require smoothly varying waveguide separations. Here…
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…
Phase-locking in cascaded stimulated Brillouin scattering
Thomas F. S. Büttner, Christopher G. Poulton, M. J. Steel +2
Cascaded stimulated Brillouin scattering (SBS) is a complex nonlinear optical process that results in the generation of several optical waves that are frequency shifted by an acous…
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…
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…
