Stimulated Brillouin Scattering in Dispersion Decreasing Fiber

Abstract

This paper reports the effects of stimulated Brillouin scattering (SBS) in dispersion decreasing fiber (DDF) with various inputs and power. The investigation into SBS includes experiments with a DFB laser, an externally modulated DFB laser, CW laser, a CW laser modulated with a Mach-Zehnder modulator, and a mode-locked picosecond laser. With these experiments, the SBS threshold in DDF is successfully determined to depend on both linewidth and power.
