Brillouin scattering induced transparency and non-reciprocal light storage [PDF]

Frontiers in Optics 2016, 2015
AbstractStimulated Brillouin scattering is a fundamental interaction between light and travelling acoustic waves and arises primarily from electrostriction and photoelastic effects, with an interaction strength several orders of magnitude greater than that of other relevant non-linear optical processes.

Contra-intuitive features of time-domain Brillouin scattering in collinear paraxial sound and light beams

Photoacoustics, 2020
Time-domain Brillouin scattering is an opto-acousto-optical probe technique for the evaluation of transparent materials. Via optoacoustic conversion, ultrashort pump laser pulses launch coherent acoustic pulses in the sample.

Spin-orbit interaction through Brillouin scattering in nanofibers [PDF]

EPJ Web of Conferences, 2023
Spin-orbit interactions (SOI), describing the transfer of a spin degree of freedom to an orbital angular momentum (OAM), have been widely explored in recent opto-acoustic studies for applications mainly in spintronics and for topological insulators [1 ...

Brillouin light scattering of spin waves inaccessible with free-space light

Physical Review Research, 2020
Microfocus Brillouin light scattering is a powerful technique for the spectroscopic and spatial characterization of elementary excitations in materials. However, the small momentum of light limits the accessible excitations to the center of the Brillouin

Brillouin light-scattering from polymer gels [PDF]

Journal de Physique II, 1993
The experimental results of th Brillouin shift and width for poly(vinyl alcohol) and poly(vinyl chloride) gels as a function of gel network volume fraction have been analysed using the theory of Marqusee and Deutch for Brillouin light-scattering from polymer gels, incorporated with a new plausible assumption relating the speed of sound in the gel ...
