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/°C was measured for fiber gratings at 1550nm within 0°C to 120°C. This represents an improvement in temperature sensitivity that is more than 3 times than that could be achieved with a bare fiber grating.
