Simultaneous Measurement of Strain and Temperature with Hollow Core Fiber Based Intermodal Interferometer

Abstract:

A hollow core fiber based all-fiber intermodal interferometer is proposed for measurement of strain and temperature. The sensing structure is simply a short segment of hollow core silica fiber being spliced between two normal single mode fibers. The fabrication process only involves a conventional fusion splicer and a mechanical fiber cleaver. Experimental results show that sensitivities of-1.21 pm/με and 21.30 pm/°C are achieved for strain and temperature measurements, respectively.
