Abstract
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.
