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 ...

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.

Stimulated Brillouin scattering flow cytometry. [PDF]
Biomed Opt ExpressWe present the use of stimulated Brillouin scattering spectroscopy to achieve rapid measurements of cell biomechanics in a flow cytometer setup. Specifically, our stimulated Brillouin scattering flow cytometry can acquire at a rate of 200 Hz, with a spectral acquisition time of 5 ms, which marks a 10x improvement compared to previous demonstrations of ...

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 ...

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 ...
