Observation of Backward Guided-Acoustic-Wave Brillouin Scattering in Optical Fibers Using Pump–Probe Technique

We experimentally demonstrate the observation of backward (i.e., opposite of the direction of the pump) guided-acoustic-wave Brillouin scattering (GAWBS) using the pump–probe technique and investigate the spectral dependence on the pump–probe light power. We show that the signa...

description We experimentally demonstrate the observation of backward (i.e., opposite of the direction of the pump) guided-acoustic-wave Brillouin scattering (GAWBS) using the pump–probe technique and investigate the spectral dependence on the pump–probe light power. We show that the signal-to-noise ratio (SNR) of the backward GAWBS measurement can be drastically improved by using this technique. We also observe a nonmonotonic dependence of the SNR on the probe power, which indicates that optimal probe power exists for implementing GAWBS-based distributed sensors.
