Paper Abstract

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 silverrecoated 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 °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.
