Intrinsic Fabry-Pe/spl acute/rot fiber sensor for temperature and strain measurements

This letter presents an intrinsic Fabry-Pe/spl acute/rot interferometric sensor fabricated by splicing a section of multimode fiber in between two single-mode fibers. The fabrication process only involves fusion splicing and cleaving. The sensor is analyzed and the issues in sensor fabrication are discussed. The sensor temperature and strain measurement performance is evaluated. The sensor may find its application in quasi-distributed sensing due to its low insertion loss.
