Abstract

We demonstrate a high sensitivity humidity sensor based on side-polished hole-assisted dual-core fiber. The experiment results show that the maximum RH sensitivity is -18.94 nm/%RH in the RH range of 70% - 90%. Due to the super-high sensitivity, the proposed sensor will be expected to be a promising candidate for highly sensitive RH sensing applications in high humidity environment.
