Continuous-wave-pumped modulational instability in an optical fiber has been demonstrated for the first time to our knowledge by using a 5-km single-mode fiber that has a small core area and anomalous group-velocity dispersion. This cw-pumped modulational instability has permitted the generation of a continuous optical pulse train with a pulse repetition rate of greater than 100 GHz, although stimulated Brillouin scattering occurred along with the modulational instability.
