| Abstract(in English) | To suppress Stimulated Brillouin Scattering (SBS), we fabricated a fiber with 3-layered GeO_2-F concentration distribution. By adjusting the concentration distribution of GeO_2-F in the core region, the same refractive index as SMF but the different acoustic velocity distributions which changes gradually along the core radius was realized. By controlling the interaction between light and acoustic modes including higher order modes, SBS threshold was successfully improved as about 6dB comparing with standard SMF keeping similar optical properties. As expected from the result of simulation, four peaks which have uniform intensity were measured in the Brillouin Gain Spectrum. It was certified that control of GeO_2-F concentration distribution is effective to suppress SBS. |
