Laser diode-based optical chaos is attractive for the fundamental physics as well as practical tasks in such as secure communications, random number generation, and fiber sensing. The characteristics of Brillouin backscattering light generated by injecting a chaotic laser into a single mode fiber have been investigated experimentally. The Brillouin backscattering light still has the chaotic properties, and the position of the chaotic anti-Stokes frequency appears a dip, which has never been reported before. The power and linewidth variations of the Brillouin Stokes light and anti-Stokes light along with the input optical power also are analyzed. Particularly, we investigate the differences of Brillouin backscattering light between chaotic laser and narrow-linewidth laser, and analyze the interacted optical spectra when the chaotic laser and the narrow-linewidth laser inject into the 10 km single mode fiber simultaneously. With detailed analysis and experimental validation, we demonstrate that due to the chaotic self-similarity property, the chaotic laser at the location of anti-Stokes frequency transforms into the Stokes light in the stimulated Brillouin scattering process, which leads to the appearing of the dip.
