A high-sensitivity bending sensor based on multi-core fiber Bragg gratings (MCFBGs) is presented and demonstrated. The bending sensor is based on FBGs fabricated on the symmetric distribution cores…
We propose an approach to utilize the natural spider dragline silk (SDS) as a flexible light waveguide integrated into an optic device. SDS is utilized as an air-clad biocompatible light waveguide …
A dual-FBG and F-P cavity compound optical fiber sensor based on a multi-core fiber (MCF) is proposed. A hollow core fiber (HCF) was fused between a single-mode fiber (SMF) and a MCF to form the F-…
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…
We experimentally proposed a helical long-period fiber grating (HLPG), which was produced by twisting a tri-hole fiber (THF) with arc discharge technology. The optical field distribution in THF-HLP…
We propose a temperature sensor, which consists of a composite optical waveguide (COW) sandwiched between two single mode fibers (SMFs). The COW is formed by side polishing a capillary optical fibe…
We propose and demonstrate a single fiber optical tweezer for particle multi-dimensional arrangement based on an optical bottle beam produced by concatenating a few-mode fiber and a step-index mult…
A novel optical sensor for ammonia concentration in water is demonstrated using up-conversion (UC) fluorescence intensity ratio (FIR). The sensor element consists of (i) an Er 3+ -Yb 3+ co-doped te…
We propose and demonstrate a spider silk-based fiber sensor for magnetic field measurement. The spider silk plays two roles: one is the carrier of sensitive magnetic materials (Streptavidin-Biotin …
