Abstract (EN): The strain and temperature sensing characteristics of a modal interferometer based on two Bragg fibers have been investigated. The special nature of this sensor is that the two Bragg fibers used present a different external cladding shape. It appears that the sensitivity to the sensing parameters are different for the two Bragg fibers, which makes it possible to fabricate several sensing configurations based on the combination of these two Bragg fibers for strain and temperature discrimination.
