Lagrangian description of Brillouin scattering and electrostriction in nanoscale optical waveguides

open access: yesNew Journal of Physics, 2015
The diffraction of light by sound waves is known as Brillouin scattering. In optical waveguides, Brillouin scattering can arise from both bulk contributions, modelled by photoelasticity, and surface contributions, which are due to the waveguide ...

Analysis of characteristics of Mandelstam–Brillouin scattering in varieties of erbium optical fibers [PDF]

open access: yesОмский научный вестник
The research presents the results of testing the Mandelstam–Brillouin scattering parameters for several types of optical fibers doped with erbium and cerium ions. The obtained Brillouin reflectograms of different types are shown.

Brillouin and Kerr nonlinearities of a low-index silicon oxynitride platform

open access: yesAPL Photonics, 2023
Nonlinear optical effects including stimulated Brillouin scattering (SBS) and four-wave mixing (FWM) play an important role in microwave photonics, optical frequency combs, and quantum photonics.

Time-domain Brillouin Scattering as a Local Temperature Probe in Liquids

open access: yes, 2018
We present results of time-domain Brillouin scattering (TDBS) to determine the local temperature of liquids in contact to an optical transducer. TDBS is based on an ultrafast pump-probe technique to determine the light scattering frequency shift caused ...

Valley Hall effect in disordered monolayer MoS2 from first principles [PDF]

open access: yes, 2015
Electrons in certain two-dimensional crystals possess a pseudospin degree of freedom associated with the existence of two inequivalent valleys in the Brillouin zone.

Anti-Stokes scattering and Stokes scattering of stimulated Brillouin scattering cascade in high-intensity laser-plasmas interaction

open access: yes, 2017
The anti-Stokes scattering and Stokes scattering in stimulated Brillouin scattering (SBS) cascade have been researched by the Vlasov-Maxwell simulation.

Semi-classical scattering in two dimensions

open access: yes, 2008
The semi-classical limit of quantum-mechanical scattering in two dimensions (2D) is developed. We derive the Wentzel-Kramers-Brillouin and Eikonal results for 2D scattering. No backward or forward glory scattering is present in 2D.

The new very small angle neutron scattering spectrometer at Laboratoire Leon Brillouin [PDF]

open access: yes, 2007
The design and characteristics of the new very small angle neutron scattering spectrometer under construction at the Laboratoire Leon Brillouin is described. Its goal is to extend the range of scattering vectors magnitudes towards 2x10{-4} /A. The unique

Research on the System of Pulse Synthesis Pre-pump Rayleigh BOTDA technology

open access: yesMATEC Web of Conferences, 2015
The conventional Rayleigh scattering Brillouin Optical Time Domain Analysis (Rayleigh BOTDA) system adopted the leakage light ahead of the pump pulse to generate Rayleigh back-scattering light.

Phase sensitive Brillouin scattering measurements with a novel magneto-optic modulator

open access: yes, 2009
A recently reported phase sensitive Brillouin light scattering technique is improved by use of a magnetic modulator. This modulator is based on Brillouin light scattering in a thin ferrite film.
