Brillouin Optical frequency domain analysis in polymer optical fiber

We report distributed temperature measurements in a perfluorinated graded-index polymer optical fiber (POF) with 50 mu m core diameter, carried out by stimulated Brillouin scattering. Brillouin optical frequency-domain analysis (BOFDA) has been performed to extract the temperature profile along a 20-m POF fiber sample, at a nominal spatial resolution of 4 m. The results indicate that POFs are potentially useful for distributed temperature measurements based on stimulated Brillouin scattering.
