A Multi-Wavelength Brillouin-Erbium Fiber Laser With Triple-Brillouin-Frequency Spacing

We demonstrate a simple multi-wavelength Brillouin-erbium fiber laser (MBEFL) with triple Brillouin frequency shift interval. The single, double, and triple Brillouin frequency spaced multi-wavelength of the MBEFL is investigated in this paper. The output of the MBEFL is optimized by adjusting the output power and wavelength of the Brillouin pump (BP) and the 980 nm pump power of the erbium-doped fiber amplifier (EDFA). In the experiment, when setting the BP power to 2.5 mw and BP wavelength to 1530.33 nm and the 980 nm pump power of EDFA1 and EDFA2 to 286 mw, 330mw, respectively, up to 11 multi-wavelength with triple Brillouin frequency shift interval is obtained. The output wavelength is tunable from 1529.55nm to 1561.01nm. The proposed multi-wavelength optical fiber laser has potential applications in the areas of space optical communication and optical communications and microwave signal source.
