Temperature characterization of nanoparticles-doped fiber in the context of transmission-reflection analysis

We present the results of temperature characterization of Mg-Er-doped fiber up to 250°C. We investigate the cause of this nanoparticles-doped fiber sensitivity by comparing our results to single mode fiber and Erbium-doped fiber under temperature variations from 20°C to 80°C. Acrylate coating does not seem to influence fibers’ temperature sensitivity, but Erbium appears to be a significant element in this study. The nanoparticles-doped fiber does not have a linear response to temperature variations and there is a drift between the increase and the decrease of the temperature. We estimate the sensitivity to be 150 nW/°C from 20°C to 100°C and 85 nW/°C from 100°C to 250°C.
