Abstract
The fabrication and optimization of regenerated Bragg gratings (RBGs) in hydrogen loaded single mode optical fibers (SMF) are presented. In addition to standard Ge-doped SMF, two kinds of B-Ge codoped SMFs with different doping concentrations are prepared using plasma-activated chemical vapor deposition (PCVD) technique to fabricate RBGs. The effects of doping concentrations on the dynamics of grating regeneration and the thermal stability of RBGs are experimentally investigated. The reflectivity of RBGs with length of 10 mm was enhanced from 20% to 40% through the optimization of doping concentrations. All fabricated RBGs can sustain in high temperature up to 1000 °C.
