All-optical tunable slow light technology has promising applications in all-optical network and optical information process. Tunable slow light based on stimulated Brillouin scattering is experimentally investigated, using highly nonlinear microstructured fiber which is designed and drawn by ourselves. The experiment setup is composed of single pump and a single-stage delay. When the pump power reaches 162.6 mW, a maximum delay of 76 ns, equal to 0.76 pulse width, is achieved in the highly nonlinear microstructured fiber of 120 m in length. In addition, by adjusting the pump power, the tunable slow light can be realized. This scheme of slow light has advantages such as large delay, being all-optical tunable and compatible with optical communications systems.
