Experimental study of temperature sensitivity fiber grating component packaged with mixed polymers

By packaging fiber gratings with two different polymers mixed at the definite rate, the temperature sensitivity experiments of the grating packaging component have been studied. The experiments indicate that the grating component has fine linear temperature sensitivity in the normal temperature range between 20 degree(s)C and 80 degree(s)C, and has good temperature sensitivity in the high temperature range between 100 degree(s)C and 300 degree(s)C, which comes close to the temperature sensitivity of the bare fiber grating.
