摘要：

We have successfully fabricated regenerated gratings (RGs) with silver coating in standard telecommunication fibers by annealing and magnetron sputtering (MG) process. Optical testing showed that the optical properties of the silver-recoated RGs were slightly affected by MG process. We performed thermal tests to evaluate the characteristics with respect to a silver-recoated RG (SRCRG) sensor within the temperature of up to 600 degrees C. The experimental results showed that the SRCRG sensor exhibited a satisfactory performance for its sensitivity, repeatability and stability. Results from the experiments also revealed that the silver coating achieved good adhesion to fiber and could be used as a conductive layer for the further electroplating process.
