Abstract :
A multi-wavelength Brillouin fiber laser (BFL) with 200nm (1430 nm to 1630 nm) wavelength tuning is presented. The BFL configuration comprises of a long 25-km SMF-28 to provide non-linear gain and optical circulator to re-inject higher order Stokes signal into cavity to seed a cascaded BFL lines. The proposed configuration produced up to 17 Brillouin Stoke lines with channel spacing of 11GHz in 1510 nm region. Reduced number of Stokes at 1430 nm and 1630 nm region is believed due to high BFL threshold. The threshold of Stimulated Brillouin Scattering (SBS) and resonance threshold of BFL was investigated experimentally and theoretically and the experimental results are well agreed with the theoretical values.
