Paper Abstract

We demonstrate a novel configuration for Brillouin optical time domain analysis based on single-sideband modulation and RF shaping that provides pump pulses with 80 dB extinction ratio. This extremely reduced leakage, which to our knowledge is the lowest ever achieved, completely suppresses distortion of the measured spectra, thus sensor precision is enhanced. Furthermore, the proposed setup results in a simplified system with only one modulator and no need for optical filtering in detection.
