Abstract
In this paper, we present a new kind of way to produce the fiber Bragg grating, in which a Fresnel prism is used as an interferometer. Comparing with the traditional holograph interferometer, the new method involves a lot of advantages. Based on the grating we have made with this method, we set up a sensor system to research its temperature characteristic. In order to increase the ratio of signal to noise, a tunable extra-cavity semiconductor laser is used as a light source instead of traditional wide-band source. The result of temperature has also been present in this paper, from which the sensitivity coefficient can be gotten.
