چکیده
A D-shaped elliptical hollow core fiber surface plasmon resonance (SPR) sensor is proposed and analyzed here using gold titanium oxide (TiO 2 ) layer. The geometry consists of a doped with concentric central air hole. finite element method-based simulation software COMSOL Multiphysics used for numerical analysis. Both TiO layers are optimized. responds over wide range refractive index (RI) from 1.33 to 1.40. average sensitivity obtained the designed 4142.85nm/RIU (RI Unit) whereas that single mode (SMF) only 897.55nm/RIU. So, our gives more than 4 times enhanced proves be potential alternative SMF based low cost, compatible SPR sensors by covering issue suffered sensors.

Gas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber
One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...
متن کاملProperties of elliptical-core two-mode fiber.
Polarization and modal birefringence of elliptical-core two-mode fibers are investigated. Wavelengths corresponding to zero group delay difference (GDD) between the two spatial modes and between the orthogonal polarizations are computed when the fiber parameters, i.e., the relative core/cladding index difference and the ratio of major over minor axis, are varied. Simple relationships between th...
متن کاملApplication of Negative Curvature Hollow-Core Fiber in an Optical Fiber Sensor Setup for Multiphoton Spectroscopy
In this paper, an application of negative curvature hollow core fiber (NCHCF) in an all-fiber, multiphoton fluorescence sensor setup is presented. The dispersion parameter (D) of this fiber does not exceed the value of 5 ps/nm × km across the optical spectrum of (680-750) nm, making it well suited for the purpose of multiphoton excitation of biological fluorophores. Employing 1.5 m of this fibe...

متن کاملHollow-core microstructured polymer optical fiber.
We have fabricated microstructured polymer optical fibers that guide light in a hollow core using the photonic bandgap mechanism. The hollow core allows the use of polymer fibers to be extended to wavelength ranges where material absorption typically prohibits their use, with attenuation lower than the material loss observed in the infrared. The fabrication method is similar to other microstruc...
