The temperature dependence of fluorescence in erbium-doped silica fiber between ~-30 and ~150°C is discussed. 980nm pumping configuration is used in our experiment. 1450nm and 1531nm wavelengths are chosen to calculate the FIR (fluorescence intensity ratio) at the first time instead of the mostly used wavelengths 525nm and 550nm. It shows that as the temperature increases, the fluorescence intensity increases obviously at short wavelengths but changes a little at long wavelengths. The temperature coefficient can achieve ~0.023dB/°C, and its resolution is improved as the temperature decreases. Because there are many effects in our experiments, so it shows a deviation from the behavior of simulation.
