From output results, 90 % output coupling ratio has ability to provide the maximum average output power of 43 dBm at Brillouin pump power of 20 dBm and Raman pump power of 14 dBm. In multi-wavelength Brillouin-Raman fiber, single mode fiber is utilized as the nonlinear gain medium. Multi-wavelength fiber lasers based on hybrid Brillouin-Raman gain configuration supported by Rayleigh scattering effect have attracted significant research interest due to its ability to produced multi-wavelength signals from a single light source.
This laser system is operates in S-band wavelength region due to vast demanding on transmitting the information. Raman amplifieraverage power model is employed for signal amplification. This paper is focusing on simulation and analyzed of S-band multi-wavelength Brillouin-Raman fiber laser performance utilizing fiber Bragg grating and Raman amplifier in ring cavity by using Optisystem software.
