We demonstrate a theoretical analysis and the experimental confirmation of the effects of Brillouin slow light on intensity-modulated waveforms in optical fibers. The results show that the DC and the AC parts of the waveform experience different Brillouin gain according to the modulation frequency, and the time delay of the intensity-modulated signal can be used to directly measure the phase-index change of the slow light configuration.
