Fiber Bragg grating (FBG) sensor system is a powerful method of detecting strain and temperature of a structure, and is put in practical use widely. However, a general FBG sensor system has a fault without tolerance in high temperature. We performed the micro fabrication in the silica fiber by the point by point method using femtosecond pulse laser. As a result, we succeeded in heat-resistant creation of FBG.
