Abstract

A Simple method for enhancing fiber grating temperature sensitivity using an aluminum tube or aluminum plate packaging is presented. Bragg wavelength shift of about 0.038 nm/℃ was measured for fiber gratings at 1550 nm within 0 ℃ to 120 ℃. This represents an improvement in temperature sensitivity that is more than 3 times than that could be achieved with a bare fiber grating.
