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/°C and significantly higher when compared with others conventional Hi‐Bi fibers. Strain experiments were also performed. © 2008 Wiley Periodicals, Inc. Microwave Opt Technol Lett 50: 3152–3154, 2008; Published online in Wiley InterScience (www.interscience.wiley.com).
