Optic fiber sensors for refractive index (RI) measurement have brought about widespread attention in an extensive range owing to their unique properties. In this paper, we theoretically analyzed an…
In this paper, an all-single-mode fiber strain sensor based on a bent structure Mach-Zehnder interferometer (BS-MZI) is proposed. This sensor consists of two identical bent structures, one of which…
In this paper, we propose the CO 2 laser polishing method to prepare a novel type of incline plane-shaped long period fiber grating (IPS-LPFG) for strain measurement. This structure is achieved by …
A novel refractometer based on multimode fiber (MMF) embedded single mode-no core-single mode (ME-SNS) fiber structure is presented and investigated in detail. The ME-SNS structure has a higher ref…
