Comparing with uncoated LPFGs, ZnO coated LPFG shows obvious improvement of RI sensitivity between the RI range of 1.4 and 1.62. The proposed structure exhibits a very high sensitivity of 5175 nm/RIU in the RI range from 1.444 to 1.448, and the sensitivity could be further improved by optimizing the thickness of the ZnO thin film.
We demonstrated a high-robustness Fabry-Perot interferometer strain sensor based on an in-fiber elliptical bubble that was created by splicing together two sections of standard single mode fibers. Such a FPI could be used to develop a high-robustness strain sensor with a low cross-sensitivity between temperature and tensile stain. The sensitivity of this strain sensor was ∼2.4 pm/με, and exhibited...
