Zero-broadening Measurement in Brillouin based Slow-light Delays

A novel method for the achievement of zero-broadening in a SBS based slow-light system is discussed in theory and demonstrated
experimentally. The system is realized just with a single broadened Brillouin gain. It is shown, that if the gain bandwidth is much broader than the initial pulse width, the output pulse width decreases with increasing pump power. A compression of approximately 90 % of the initial pulse width was achieved in simulation and experiment.
