Abstract
A long optically controlled delay line enhanced by ring configurationis demonstrated by using the group-velocity control of signal pulsesbased on stimulated Brillouin scattering. In experiment, two opticalfibre ring cavities are used: one is used as the Brillouin laser,providing single-mode Stokes wave as probe wave; the other is used asthe Brillouin amplifier, working as slow light medium. We achieve amaximum time delay of 215 ns using the ring Brillouin amplifier, fivetimes larger than the input probe pulse width of 40 ns. In themeantime, a considerable pulse broadening is observed, which agreeswell with the theoretical prediction based on linear theory.
