Reflective liquid level sensor based on modes conversion in thin-core fiber incorporating titled fiber Bragg grating
A simple and compact reflective liquid level sensor based on modes conversion in the thin-core fiber incorporating one tilted fiber Bragg grating (TFBG) is proposed and experimentally demonstrated. A piece of thin-core ...
Simultaneous Measurement of Torsion and Temperature Based on Helical Structure in Multicore Fiber
An all-fiber torsion sensor based on a helical structure in a multicore fiber is demonstrated. The sensor exhibits the ability of discriminating torsion direction, torsion angle and temperature.
Hybrid Graphene/Gold Plasmonic Fiber-Optic Biosensor
A 2D material/metal hybrid plasmonic sensor is demonstrated by direct integration of graphene layer on gold-coated optical fiber. Both linear response to wide range ssDNA concentration from 1 × 10−12 to 10 × 10−6m and low ...
Directional torsion and temperature discrimination based on a multicore fiber with a helical structure
We propose and experimentally demonstrate a directional torsion sensor based on a Mach-Zehnder interferometer formed in a multicore fiber (MCF) with a ~570-μm-long helical structure (HS). The HS was fabricated into the MCF ...
Design and analysis of surface plasmon resonance sensor based on high-birefringent microstructured optical fiber
Optical fiber based surface plasmon resonance (SPR) sensors are favored by their high sensitivity, compactness, remote and in situ sensing capabilities. Microstructured optical fibers (MOFs) possess microfluidic channels ...
Ultra-sensitive chemical and biological analysis via specialty fibers with built-in microstructured optofluidic channels
All-in-fiber optofluidics is an analytical tool that provides enhanced sensing performance with simplified analyzing system design. Currently, its advance is limited either by complicated liquid manipulation and light ...
