Abstract

We propose a delay line configuration to increase the time delay performance of multiple-pump-line Brillouin-based slow light systems. It consists of several short fibers interconnected by filters to block degrading spectral components. Three different delay line configurations are investigated experimentally with an optimized Brillouin spectrum composed of a superposition of a gain with two losses. An increase of the maximum time delay by 12% is reported, which is limited by the insufficient filter slew rates. We believe that the enhancement could be much higher by using filters with an improved slew rate performance.
