Paper Abstract

We present preliminary results on the feasibility demonstration of using the rare-earth-doped silica as the IR-to-visible converter. Its principle of operation employs the up-conversion upon pumping with the near IR radiation. The simulation results of the time-dependent 3-D heat transfer study demonstrate the spatial and temporal resolution of this transducer for the constant and impulse irradiation profile, confirming the concept when the Er-doped silica fiber is in contact with a cold reservoir. The preliminary experimental results confirm the feasibility of using the converter for room temperature applications, that correspond to about 10-μm radiation. The error arising from the rare-earth dopant non-uniformity is estimated at +/- 1.5 C.
