Abstract: There are important applications for stimulated Brillouin scattering slow light in all
work. This paper reports that slow-light delays in designed and drawn
highly nonlinear microstructured fiber induced by stimulated Brillouin scattering is numerically
studied. The signal pulse output waveform curve of the microstructured fiber can be simulated
numerically. Variation of time delay and pulse broadening of signal pulse are analyzed. The
results show that the influence of pump power, pulse width and center wavelength on delay time
and the effect of microstructured fiber dispersion on pulse shape is also analyzed. The demand of
pump power is effectively reduced when this kind of fiber is used, and the fiber has a large
potential use in stimulated Brillouin scattering slow light system.
