摘要

We propose a novel scheme for simultaneous strain and temperature measurement by mode division multiplexing (MDM) in a dual cladding modes fiber up-taper interferometer. The fiber interferometer, with a strong cladding mode and a weak cladding mode, can be constructed by fabricating two optimized adjacent fiber up-tapers along a single-mode fiber. With the MDM method, the temperature and strain measurement resolutions reach +/- 0.05 degrees C and +/- 3.14 mu epsilon, respectively, which are much higher than those of the other proposed dual-parameters (temperature and strain) measurement solutions.
