基于半导体激光器的光学混沌不仅在基础物理领域有着广泛的应用前景，而且在保密通信、随机数产生、光纤传感等领域也有着广泛的应用前景。实验研究了混沌激光注入单模光纤产生的布里渊后向散射光的特性。布里渊后向散射光仍然具有混沌特性，并且混沌反斯托克斯频率的位置出现了一个凹陷，这是以前从未报道过的。分析了布里渊斯托克斯光和反斯托克斯光的功率和线宽沿着输入光功率的变化。研究了混沌激光与窄线宽激光在布里渊后向散射光的差异，分析了混沌激光与窄线宽激光同时注入10 km单模光纤时，两种激光相互作用的光谱。通过详细的理论分析和实验验证，证明了由于混沌自相似性，反斯托克斯频率处的混沌激光在受激布里渊散射过程中转变为斯托克斯光，从而导致凹陷的出现。
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.
