We propose and demonstrate a thinned fiber based Mach-Zehnder interferometer for multi-purpose sensing applications. The sensor head is formed by all-fiber in-line singlemode-multimode-thinned-singlemode (SMTS) structure, only using the splicing method. principle of operation relies on effect that cladding modes interference with core mode employing multimode as coupler. Experimental results showed liquid refractive index information can be simultaneously provided from measuring sensitivity...
A facile solvothermal approach was used to synthesize ultrasmall monodisperse magnetite (Fe3O4) nanoparticles with precise size control of one nanometre, in which iron acetylacetonate [Fe(acac)3] acted as the source, n-octylamine reductant, and n-octanol solvent. By varying volume ratios n-octanol, 4 nm, 5 nm 6 Fe3O4 were obtained. Compared popular thermal decomposition methods nanoparticles, this process, without need for a N2 atmosphere reflux conditions, more convenient. The intrinsic...
We present and numerically characterize a closed-form multi-core holey fiber based plasmonic sensor. The coupling properties of the specific modes are investigated comprehensively by finite element method. It is found that not only phase matching but also loss plays key role in process between fundamental mode mode. transforms from incomplete to complete with increasing analyte RI. An average sensitivity 2929.39 nm/RIU sensing range 1.33-1.42, 9231.27 1.43-1.53 high linearity obtained....
A novel D-shaped photonic crystal fiber refractive index sensor based on surface plasmon resonance (SPR) is proposed and numerically studied. Different from the normal structures, we here used an open-ring channel coated with gold film to excite plamonic modes. The coupling properties sensing performance of this structure are analyzed using finite element method. Simulation results indicate that has a range 1.20 1.29. When analyte (RI) above 1.25, anti-crossing effect starts appear, peak...
We present and numerically characterize a liquid-core photonic crystal fiber based plasmonic sensor. The coupling properties sensing performance are investigated by the finite element method. It is found that not only mode dispersion relation but also fundamental rather sensitive to analyte refractive index (RI). positive negative RI sensitivity coexist in proposed design. features when increment of SPP effective larger than mode, sensor shows once gets larger. A maximum -5500nm/RIU...
A novel flexible room temperature ethanol gas sensor was fabricated and demonstrated in this paper. The polyimide (PI) substrate-based formed by depositing a mixture of SnO2 nanopowder poly-diallyldimethylammonium chloride (PDDAC) on as-patterned interdigitated electrodes. PDDAC acted both as the binder, promoting adhesion between PI substrate, dopant. We found that response SnO2-PDDAC is significantly higher than alone, indicating doping with effectively improved performance. has detection...
BackgroundThe Zingiberaceae family serves as a diverse repository of bioactive phytochemicals, comprising approximately 52 genera and 1300 species aromatic perennial herbs distinguished by their distinct creeping horizontal or tuberous rhizomes. Amomum villosum Lour. tsao-ko Crevost & Lemaire., are the important plants that have been widely used in traditional medicine for treatment many ailments. The employed qualities valued spices flavorings. In essential oils (EOs) species, notable...
High flatness, wide bandwidth, and high-coherence properties of supercontinuum (SC) generation in fibers are crucial many applications. It is challenging to achieve SC spectra a combination the properties, since special dispersion profiles required, especially when pump pulses with duration over 100 fs employed. We propose an all-solid microstructured fiber composed only hexagonal glass elements. The optimized possesses ultraflat all-normal profile, covering wavelength interval approximately...
We investigate the nonmonotonic behavior observed in timelike nucleon electromagnetic form factors. Using a phenomenological extending vector meson dominance model, where ground states $\ensuremath{\rho}$ and $\ensuremath{\omega}$ their excited $\ensuremath{\rho}(2D)$, $\ensuremath{\omega}(3D)$, $\ensuremath{\omega}(5S)$ are taken into account, we have successfully reproduced cross sections of ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}p\overline{p}$...
