Tunable bistability in hybrid Brillouin–erbium single-frequency fiber laser with saturable absorber
TL;DR: In this paper, a single-frequency hybrid Brillouin-erbium fiber laser with a saturable absorber is used to suppress the multiple-longitudinal mode operation. But the results show that the proposed fiber laser performs a single longitudinal mode status with excellent stability of the output wavelength and optical power.

Superluminal propagation through 500 m optical fiber via stimulated Brillouin scattering.
TL;DR: Brillouin-induced loss resonance for fast light generation of pump signals is achieved in a single frequency Brillouin lasing oscillator with a highly nonlinear fiber as the SBS medium, which is the longest superluminal propagating distance reported so far.

Enhanced negative group velocity propagation in a highly nonlinear fiber cavity via lased stimulated Brillouin scattering
TL;DR: In this paper, a 10-m highly nonlinear fiber (HNLF) ring cavity was used for negative group velocity superluminal propagation with high Brillouin gain coefficient and the optimized 1∕99 coupler ratio.
Dynamics and limitations of superluminal propagation based on long-cavity Brillouin fiber lasing oscillation
TL;DR: In this article, the authors theoretically analyzed and evaluated the mechanism of superluminal propagation in a long-cavity Brillouin fiber laser system and derived the formulation of the fractional advancement considering the impact of the pump power spectral density and the modulation frequency.
