Abstract
In this letter, a temperature sensor using a fiber loop mirror containing a piece of highly birefringent erbium doped fiber is presented. A Hi-Bi PANDA erbium-doped silica fiber was used and compared with the conventional Hi-Bi PANDA fiber. Different results for strain and temperature sensitivity were obtained. The temperature coefficient sensitivity was -2.22 nm/degrees C and significantly higher when compared with others conventional Hi-Bi fibers. Strain experiments were also performed.
