We experimentally demonstrate complete compensation of pulse\udbroadening in an amplifier-based slow light system. The configuration of\udthe delay line basically consists of two stages: a conventional Brillouin slow\udlight system and a nonlinear regeneration element. Signal pulses\udexperienced both time delay and temporal broadening through the Brillouin\uddelay line and then the delayed pulses were delivered into a nonlinear\udoptical loop mirror. Due to the nonlinear response of the transmission of the\udfiber loop, the inevitably broadened pulses were moderately compressed in\udthe output of the loop, without loss in the capacity to delay the pulses. The\udoverall result is that, for the maximum delay, the width of the pulse could be\udkept below the input width while the time delays introduced by the slow\udlight element were preserved. Using this delay line, a signal pulse with\udduration of 27 ns at full width at half maximum was delayed up to 1.3-bits\udwithout suffering from signal distortion.
