A Bragg wavelength shift of about 0.038 nm/degree Celsius was measured for fiber gratings centered around 1550 nm for a temperature range of 0 degrees Celsius to 120 degrees Celsius. This represents an improvement in temperature sensitivity that is 3.2 times than that could be achieved with a bare fiber grating and enables the design of more sensitive temperature sensors.
