Paper Abstract

This work introduces the experimental results of a temperature sensor device, with doped fiber and LPGs. The device is introduced in a temperature controlled oven, observing a 1 nm shift in wavelength toward longer wavelengths when the temperature increases 3 °C. It is possible to observe the average rate of change in the power related to increased temperature for two and three fiber gratings temperature sensors, and finally it is noted that the channels generated by the interference pattern are dispersed as temperature increases. The experiment was performed for 2 and 3 LPFGs in series where the wavelength displacement, output power and the number of channels were analyzed when the temperature was increased.
