摘要：We demonstrate a novel method to build a tunable fiber-optic delay line based on stimulated Brillouin scattering (SBS) in a single-mode optical fiber. The frequency of a continuous-wave lightwave served as the Brillouin probe is linearly swept to determine the location in the fiber where a pulse signal served as the Brillouin pump is reflected and thus delayed via SBS-intensified acoustic grating. The novel fiber-optic delay line has a linear tunability of more than 4 µs. The pulse distortion is also studied.
