摘      要:A new single-mode fibre(SMF)with high stimulated Brillouin scattering(SBS)threshold which is co-doped with GeO_(2) and F_(2) in the core is *** increase the SBS threshold,the acousto−optic effective area is increased by designing a transverse acoustic waveguide and adjusting the doping level of GeO2 and F2 while the designed fiber retains a step optical refractive index *** optimal design is found by numerical simulation and the optimal fiber is fabricated by a plasma−activated chemical vapor deposition(PCVD)*** yields the threshold 6.79 dB,which is higher than the conventional single-mode fiber G.652 and 3dB higher than the Corning®SMF−28e+^(™)optical fiber with NexCor®technology.
