A refractive index insensitive triple cladding quartz specialty fiber temperature sensor with D-type microcavity structure is proposed. It consists of a fiber(TCQSF) fused between two sections single-mode fiber(SMF). Because the SMF and TCQSF mode fields do not match, excited modes form Mach-Zehnder(M-Z) interferometer, resulting in interference phenomenon. Experimental results show that range 30-90°C, transmission spectrum has red shift phenomenon, sensitivity 138.03 pm/°C, wavelength good...
In this paper, an Ag nanoparticles (AgNPs) modified multimode fiber (MMF) SERS probe prepared based on sol self-assembly method is proposed and fabricated. Different probes (AgNPs-MMF-x, x the time) are obtained by adjusting time. Using rhodamine 6G (R6G) solution as molecule, far-end performances of studied, AgNPs-MMF-30 with obvious advantages in performance obtained. The limit detection (LOD) for R6G low 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...
In this paper, a dual-parameter sensor for the measurement of temperature and strain with double air-gaps structure based on graded-index few mode fiber (GI-FMF) is proposed fabricated. Two sections GI-FMF are used: one end them etched HF acid to form an air-gaps, other cut flat. Next, single-mode these two GI-FMFs spliced successively structure. A four-beam interferometer formed sensing principle established. The response characteristics analyzed in experiment. reflection spectrum divided...
