Abstract

Stimulated Brillouin scattering (SBS) can amplify the light propagating in a direction opposite to the pump light. It has many applications such as optical amplification, lasing, optical fiber sensor, optical phase conjugation, slow light generation and stored light. In the case of slow light generation via SBS, tunable all optical delay lines via SBS using an optical fiber have been demonstrated [1], which shows that SBS delay line is a promising candidate for all-optical buffers in optical communication system. For all the Brillouin slow light systems, time delay is always accompanied by the pulse distortion. To reduce the pulse distortion effects, Brillouin slow light system based on doublet gain lines was suggested by Stenner et al [2]. Very recently, Schneider et al [3] reported zero-broadening Brillouin slow light in an optical fiber while accompanying with large pulse distortion.
