Abstract: An embedded fiber Bragg grating (FBG) sensor, which fabricated in IMS, for temperature sensing was proposed. The temperature responses of the in-fiber Bragg gratings (FBGs) have been investigated. It was found that these responses ranged from 10.6 pm/°c to 12.0 pm/°c. The temperature sensitivity of the FBGs was 0.2°c. The strain responses remained temperature independent over a temperature range of 20 - 180 ’c . The results obtained are in agreement, within the experimental error, with predictions based on material parameters. Although the temperature response is nonlinear over the temperature range 20°c to 180°c , in practical systems the temperaturc response of the sensor may be assumed to be linear within the temperature range 20°c to 80°c.
