We proposed and experimentally investigated the torsion sensing performance of tilted long period gratings (TLPG) based on eccentric dual core fiber (EDCF). The EDCF is composed a centric an with large separation. asymmetrical structure high refractive index modulation TLPG can bring some directional sensitivity advantages to structure. tested torsional in two optical channels different grating parameters found both cores recognize direction. When tilt angle 80°, maximum are −0.381...
A metasurface is a two-dimensional structure with subwavelength thickness that can be used to control electromagnetic waves. The integration of optical fibers and metasurfaces has received much attention in recent years. This integrated device high flexibility versatility. We propose an based on fiber-integrated the mid-infrared, which uses hollow core anti-resonant fiber (HC-ARF) confine light transmission air core. bilayer at end face achieve transmissive modulation field emitted from...
Pressure sensitivity and gas desorption time are two key parameters that determine the performance of pressure sensors. Polydimethylsiloxane (PDMS) film shows potential in highly sensitive sensor, however trade-off between high low presents a challenge. This article proposes novel sensor with ultra-high ultra-fast based on tapered fiber coated Polydimethylsiloxane/Metal Organic Framework (PDMS/MOF) composite film. By doping specific MOF amino groups into PDMS, adsorption capacity can be...
In this paper, a Mach-Zehnder interference (MZI) based on asymmetric tapershaped ultraviolet glue is proposed for highly sensitive temperature sensing. Due to the small diameter and deflected two ends of tapered UV glue, part light leaked into air during propagation taper, resulting in interference. We tested sensing several samples with different parameters. Experimental results show that increase temperature, wavelength moves linearly shorter wavelength. range 5 °C- 9 °C, highest...
A highly sensitive fiber temperature sensor based on Vernier-like effect and composite Fabry-Perot interferometers (FPIs) constructed with photopolymer probe is proposed. The FPIs consists of two probes form the interference cavities air, in which sides air cavity are photopolymer. Therefore, both to their free spectral ranges (FSR) close enough meet conditions effect. sensitivity measured as high -90nm/℃, 30 times FPI a single probe. In addition, preparation process, directly attached end...
