Abstract

We demonstrate a wavelength-transparent stimulated-Brillouin-scattering (SBS) approach for slow light. Our approach makes use of a cross-gain-modulation-based wavelength converter and a Brillouin fiber laser. The input wavelength is converted to become spectrally aligned to the resonance induced by SBS. The maximum delay achieved is $26\mathrm{ns}$ with a $30\mathrm{dB}$ Brillouin gain. The delay variation is less than $0.2\mathrm{ns}$ over 40 nm wavelength detuning of the input signal.
