Dynamic Strain Measurement Using Small Gain Stimulated Brillouin Scattering in STFT-BOTDR

Near-forward Stimulated Brillouin Scattering

LLE Review, Volume 72 177 In stimulated Brillouin scattering1 (SBS) an incident (pump) light wave is scattered by the electron-density fluctuations associated with an ion-acoustic (sound) wave. This process generates a frequency-upshifted (anti-Stokes) light wave and a frequency-downshifted (Stokes) light wave. For most scattering angles the anti-Stokes wave is driven nonresonantly and can be n...

Stimulated Brillouin Scattering Microscopic Imaging

Two-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. Nonlinear Brillouin scattering spectroscopy and microscopy may provide a way to tremendously accele...

Suppression of Stimulated Brillouin Scattering

Four-Wave Mixing Bandwidth Enlargement Using Phase-Matching Control by Gain-Transparent Stimulated Brillouin Scattering

We demonstrate an optical approach to control fourwave mixing (FWM) conversion bandwidth based on gaintransparent stimulated Brillouin scattering (SBS) in fiber. By introducing self-compensation of optical gain/loss with frequency-locked SBS pump and Stokes waves, the FWM phase matching condition can be flexibly controlled through SBS induced refractive index change without affecting the signal...
