S-band dual cavity multiwavelength Brillouin Raman fiber laser employing dual Raman amplifier

摘要

In this paper, we propose and demonstrate a simulation of dual cavity multiwavelength Brillouin Raman fiber laser utilizing dual Raman amplifier with a tuning range between 1460 nm to 1530 nm. The proposed configuration utilizes 7 km single mode fiber and 7 km of Raman amplifier to generate the Stimulated Brillouin Scattering and Stimulated Raman scattering effect, respectively. The Brillouin pump and Raman pump power are optimized in order to produce maximum Brillouin Stokes power. At 15 dBm of Brillouin pump power at 1510 nm and 30 dBm of Raman pump power at 1425 nm with an output coupling ratio of 70%, this laser system generates the optimum output Brillouin Stokes power of 38.13 dBm.
