All-optical phase regeneration of a binary phase-shift keying signal is demonstrated at 10-30 Gb/s without a phase-locked loop in a phase-sensitive amplification-based system using Brillouin amplification of the idler. The system achieves phase noise reduction of up to 56% and up to 11 dB OSNR gain at 10<sup>-5</sup> bit error rate for the 10 Gb/s signal. The system's sensitivity to different parameters and stability is also evaluated.
