We proffer in this research a distinctive, facile to fabricate, and highly sensitive photonic crystal fiber (PCF) biosensor based on the phenomenon of surface plasmon resonance (SPR). Our prototype has strategic pattern circular air holes inside fiber, which leads superior sensing performance. The evaluation all sensor characteristics been discharged by employing finite element method (FEM) COMSOL Multiphysics. gold (Au) layer just around acts as plasmonic material, TiO2 increases adhesivity...
Abstract Mid-infrared (MIR) technologies are crucial for applications from chemical sensing to precision medical surgery. Effective polarization control is essential enhance the functionality of fiber systems. Current solutions in MIR primarily involve free-space devices and components. In this work, we take a step forward experimentally demonstrate conversion within soft glass fluoride chalcogenide fibers using commercially available in-line controller (PC). Our experiments single PC show...
We present an ultra-sensitive Surface Plasmon Resonance-based Photonic Crystal Fiber (SPR-PCF) sensor that can be employed for multipurpose sensing of analyte, temperature, and magnetic field. Our prototype has a trigonal cluster-based strategic pattern circular air holes inside the fiber easily fabricated using standard Stack-and-Draw method. Thin layers gold (Au) titanium dioxide (TiO2) are used as plasmonic materials surrounding PCF. The Finite Element Method (FEM) commercial software...
This paper introduces a comprehensive study of quad-cluster multi-functional Photonic Crystal Fiber (PCF) sensor where gold and Aluminum doped with zinc oxide (AZO) were used as plasmonic materials. A maximum Amplitude Sensitivity (AS) 5336 RIU−1 Wavelength (WS) 40,500 nm/RIU in y pol was obtained incorporating Gold material. When AZO included the material, AS 3763 & WS 9100 for polarization determined. The RI detecting range increased from 1.32 to 1.43 1.19–1.42 after using instead Au that...
This study presents an investigation on the performance of sensitivity a dual spider-shaped surface plasmon resonance (SPR)-based photonic crystal fibre (PCF) refractive index sensor having unique design specifications. To evaluate guiding properties, Finite Element Method is used for utilising monetarily accessible COMSOL Multiphysics version 5.3a. A gold layer has been as plasmonic material surrounding to ensure chemical stability, and single fine coating TiO2 supported improvement...
We demonstrate the first proof of concept in-line polarization control using soft-glass fibers, crucial for mid-infrared applications. ZBLAN and hybrid As 2 S 3 fibers exhibit high extinction ratios (PER) 20.8 dB 19.8 dB, respectively.
