MULTIPLE WAVELENGTH SIGNAL GENERATION FROM A BRILLOUIN ERBIUM FIBER LASER INTERNALLY PUMPED FROM FBG FIBER LASER

Abstract

A dual-ring Brillouin erbium fiber laser (BEFL) system sharing the same erbium doped fiber (EDF) had been demonstrated to output a single wavelength Stokes signal [1]. The system had been used to form a cascaded configuration for multiwavelength generation. The dual-cavity ring laser system demonstrated a multiwavelength output of 16 Stokes signals spaced at 0.088 nm. The Brillouin erbium fiber laser was in one cavity and a fiber Bragg grating (FBG) fiber laser in the other, which acted as a Brilloiun pump for the BEFL. No external Brillouin pump was used in the experiment.
