We demonstrated femtosecond laser inscription of fiber Bragg gratings (FBGs) in a twin-core few-mode fiber (TC-FMF) for directional bend sensing. An FBG was selectively inscribed in one core of the TC-FMF by using an 800 nm femtosecond laser through a phase mask. Three resonance peaks at the wavelengths of 1549.05, 1547.65, and 1546.08 nm were observed in the reflection spectrum of the TC-FM FBG,...
We demonstrate a novel polyvinyl chloride (PVC) diaphragm-based fiber-tip Fabry-Perot interferometer for gas pressure measurements with ultra-high sensitivity. The PVC diaphragm has been coated to the end facet of a well-cut standard single-mode fiber by use of a plastic welder. Ultrahigh pressure sensitivity of ∼66.07 nm/MPa at 1565 nm and a low temperature cross-sensitivity of —5.5 KPa/°C have been...
A new method to modify excessively titled fiber gratings (Ex-TFGs) with 20 nm gold nanoparticles (GNPs) through 3-mercapt-otrimethoxysilane(MPTMS) was proposed. By monitoring the wavelength shift of Ex-TFGs for every modified step and using the scanning electron microscope (SEM), it proves that GN Ps are firmly combined on the surface of Ex-TFGs. Finally, by using different concentration of NaCl solutions...
A type of newcastle disease virus (NDV) immunosensor based on 81° tiled fiber grating (81° TFG) was proposed. Staphylococcus aureus Protein A (SPA) was used to modify the surface of 81° TFG, then highly purified NDV monoclonal antibodies (MAbs) were immobilized on 81° TFG surface through SPA molecules. The experimental results show that, the immunosensor has a lowest limit of detection (LOD) of 0...
Presented in this paper is a dual routing engine-enabled optical network platform with multi-domains and multi-layers. Structure and key technologies of the platform are outlined. Experiments on it with 2 routing strategies are conducted, the results are discussed and the network scalability is evaluated.
