Visible details of the period-eight cycle route to chaotic process based on stimulated Brillouin scattering

A period-eight cycle route to chaos has been observed in a stimulated Brillouin scattering (SBS) system for the first time. Since the observation of fine periodic-orbit structure in very short dynamical region of chaotic domain is very difficult, in this work, we design a novel experiment to extend the chaotic domain by injecting light to the end of fiber and adjusting the proportion of stimulated Brillouin backscattering power and pump power, the present result shows the period-eight cycle route to chaotic laser process as well as more details of chaos. Simulations of the route to chaos are also presented.
