Wavelength-transparent, stimulated-Brillouin-scattering slow light using cross-gain-modulation-based wavelength converter and Brillouin fiber laser.
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 ns with a 30 dB Brillouin gain. The delay variation is less than 0.2 ns over 40 nm wavelength detuning of the input signal.
