Paper Abstract

We describe experimental results demonstrating the performance of the erbium-doped silica fiber as a remote temperature sensor in the temperature interval [21 C - 96 C]. We present the measured fluorescence spectrum corresponding to the energy levels 2H11/2 and 4S3/2. This sensor incorporates simple signal detection in a band and data analysis system, incorporating a power ratio to reduce noise effects. We find the channel responsivity, the power ratio, and the sensitivity for a number of possible filters. The best responsivity is above 0.2μW/C, and its sensitivity is 0.0065 C-1 with the filters transmitting in the [527 nm - 537 nm] and [545 nm - 555 nm] spectral bands. With a custom-made filter, centered on 545 nm, even higher sensitivity is predicted.
