Abstract
A technique is used to enhance the pressure and temperature sensitivity of a fiber Bragg grating sensor. The grating is packaged by using polymer jack et, which exhibits no significant chirp due to the adoption of the special technique. The measured pressure and temperature sensitivity of the structu red grating is 6.28 x 10(-5)/MPa and 5.18 x 10(-5)/degrees C. The wavelengt h shift due to pressure and temperature can be enhanced about 31.5 times fo r pressure and 7.7 times for temperature.
