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 ...

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 ...

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

Forward Brillouin scattering in few-mode fibers [PDF]
Light: Science & ApplicationsForward Brillouin scattering is an opto-mechanical effect in which two co-propagating optical fields couple with an acoustic mode in a common medium. The effect has been studied in standard optical fibers since 1985, however nearly all studies have been ...
