Abstract

In order to explore new fiber materials that can be used for discrete Raman amplifier, first and second order Raman amplifiers are designed based on TiO₂-doped fiber. A pump parameter configuration scheme with high power conversion efficiency and flat gain is given. The gain characteristics of first-order and second-order Raman amplifiers based on TiO₂-doped fiber and second-order Raman amplifiers based on GeO₂-doped fiber are compared with the same total pump power. The simulation result shows that in the 60nm bandwidth range of L-band, 32dBm pump light is injected forward into 6km long TiO₂-doped fiber to amplify 3dBm signal light. Its power conversion efficiency can reach 41.57%, and the gain flatness is only 1.14dB. Compared with the second-order Raman amplifier doped with GeO₂ fiber, it has a more stable output gain.
