Abstract :
The way to improve the reflectivity of chemical composition grating (CCG) sensors is studied. Experimental results show that improving the initial fiber Bragg grating (FBG) reflectivity strength and enhancing the hydrogen concentration in the initial FBG inscription help to increase the reflectivity of the CCG sensors at high temperatures.
