Large evanescently-induced Brillouin scattering at the surrounding of a nanofibre [PDF]
Nature Communications, 2022 The authors observe efficient Brillouin scattering generated by an evanescent field nearby a single pass sub-wavelength waveguide. This work creates an important bridge between Brillouin scattering in waveguides, Brillouin spectroscopy and microscopy.

On-chip inter-modal Brillouin scattering [PDF]
Nature Communications, 2017 Here, Kittlauset al. demonstrate stimulated inter-modal Brillouin scattering on-chip. Through this process, a Brillouin interaction couples light fields that propagate in distinct spatial modes of a Brillouin-active silicon waveguide, which may allow a ...

Brillouin scattering self-cancellation [PDF]
Nature Communications, 2016 The interaction between light and acoustic phonons is radically modified in sub-wavelength photonic structures. Here, the authors engineer the optical and acoustic modes to perfectly cancel the two interaction mechanisms—the photo-elastic and moving ...

100th Anniversary of Brillouin Scattering: Impact on Materials Science [PDF]
Materials (Basel), 2022 L. Brillouin predicted inelastic light scattering by thermally excited sound waves in 1922. Brillouin scattering is a non-contact and non-destructive method to measure sound velocity and attenuation.

Brillouin scattering spectrum for liquid detection and applications in oceanography
Opto-Electronic Advances, 2023 The Brillouin scattering spectrum has been used to investigate the properties of a liquid medium. Here, we propose an improved method based on the double-edge technique to obtain the Brillouin spectrum of a liquid.
