Abstract
Fiber Bragg grating (FBG) is an important optical passive device and widely used in optical fiber communication system. The application of normal organic polymer coating FBG used in some area is limited because of its easy annealing and aging at high temperature. Employing chemical methods, we obtain certain thickness of uniform and compact surface silver layer by controlling etching conditions and reaction time. Since the interference of the external stress, the experiment result shows that the sensitivity of temperature keeps good linear response characteristic in the meanwhile. It is proved that FBG with metal silver coating effectively improved the characteristic in its sensing area.
