Localization-assisted stimulated Brillouin scattering spectroscopy [PDF]

APL Photonics, 2022
Brillouin spectroscopy has emerged as a promising modality to noninvasively probe the mechanical properties of biologically relevant materials. Stimulated Brillouin scattering (SBS) has the potential to improve measurement speed and resolution by ...

Forward stimulated Brillouin scattering and opto-mechanical non-reciprocity in standard polarization maintaining fibres [PDF]

Light: Science & Applications, 2021
Opto-mechanical interactions in guided wave media are drawing great interest in fundamental research and applications. Forward stimulated Brillouin scattering, in particular, is widely investigated in optical fibres and photonic integrated circuits.

Stimulated Brillouin scattering of backward stimulated Raman scattering. [PDF]

Sci Rep, 2020
AbstractThe rescattering of backward stimulated Raman scattering (BSRS) by stimulated Brillouin scattering (SBS) is found in the high electron density region by relativistic Vlasov-Maxwell simulation and particle-in-cell (PIC) simulation, where the BSRS is in the regime of absolute instability and dominates in all the scatterings.

Tailorable stimulated Brillouin scattering in nanoscale silicon waveguides [PDF]

Nature Communications, 2013
Nanoscale modal confinement is known to radically enhance the effect of intrinsic Kerr and Raman nonlinearities within nanophotonic silicon waveguides. By contrast, stimulated Brillouin-scattering nonlinearities, which involve coherent coupling between ...

Improvement of gain and spatial resolution for impulsive stimulated Brillouin scattering microscopy [PDF]

Photoacoustics
Brillouin microscopy has been widely used in the mechanical imaging of cells and tissues, and the signal-to-noise (SNR) ratio limits the spectral integration time.

Metamaterial control of stimulated Brillouin scattering [PDF]

Optics Letters, 2016
Using full opto-acoustic numerical simulations, we demonstrate enhancement and suppression of the SBS gain in a metamaterial comprising a subwavelength cubic array of dielectric spheres suspended in a dielectric background material.

Stimulated Brillouin scattering flow cytometry. [PDF]

Biomed Opt Express
We 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 ...

Stimulated Brillouin Scattering Microscopic Imaging. [PDF]

Sci Rep, 2015
AbstractTwo-dimensional stimulated Brillouin scattering microscopy is demonstrated for the first time using low power continuous-wave lasers tunable around 780 nm. Spontaneous Brillouin spectroscopy has much potential for probing viscoelastic properties remotely and non-invasively on a microscopic scale.

Stimulated Brillouin scattering in metamaterials [PDF]

Journal of the Optical Society of America B, 2016
We compute the SBS gain for a metamaterial comprising a cubic lattice of dielectric spheres suspended in a background dielectric material. Theoretical methods are presented to calculate the optical, acoustic, and opto-acoustic parameters that describe ...
