Abstract

We proposed a novel scheme for simultaneous measuring strain and temperature with high sensitivity by introducing higher-order modes interference in a single-mode-twisted-multimode-single-mode(STMS) structure. The strain and temperature sensitivity reach −14.2 pm/με and 28.61 pm/°C, respectively.
