Simulation Design of Hollow Core Photonic Crystal fiber for Sensing Water Quality

Abstract

In this work we submit a simulation design to sense the water quality using hollow core photonic crystal fiber. The work of this types of optical fibers depending on the variety of structural design and geometrical parameters. The numerical results are studied by using the Finite Element Method (FEM) through COMSOL MULTIPHYSICS simulation software. Different concentrations from (0%) to (100%) of D2O and H2O2 solution in water as sensed liquid had been chosen. The studied HC-PCF investigated for analyzing the relative sensitivity, effective area and confinement loss at wavelength range from (1) µm to (2) µm.

Photonic Crystal Fiber Pollution Sensor Based on the Surface Plasmon Resonance Technology

“…SPR refers to surface Plasmon resonance and is defined as an optical phenomenon that occurs when p -polarized light excites a charge density oscillation at the metal-dielectric interface by achieving the phase matching state between the p -polarized light and SP 6 .Combining the advantages of PCF technology with plasmonic science, PCF-SPR sensors have been developed, for a wide range of potential applications such as water testing 7 , food safety, solution concentration measurement 8 , environmental monitoring, biomedical treatment 9 , gas detection, medical diagnostics, and so on 10 . The sensing mechanism of PCF-SPR is generated by means of an evanescent field.…”

“…Mahmood et al, 2018. proposed PCF-SPR sensor with maximum sensitivity of 164.3 nm/RIU in the sensing range of analyte RI 1.33-1.3431, which uses plasmonic material such as gold to coat air holes and filled with analyte sample 16 . Muhammed et al presented a hollow core photonic crystal fiber as a water quality sensor with a core of PCF filled with various concentrations of H 2 O 2 and D 2 O in water, with relative sensitivity decreasing with increasing concentration and varying between 97 percent and 67 percent for H 2 O 2 solution and between 80 percent and 41 percent for D 2 O, where relative sensitivity is dependent on effective refractive index profile 7 . In this study, however, sensor performance was significantly improved by using an internal sensing approach.…”

D-Shaped Photonic Crystal Fiber Toxic Metal Ions (Arsenic) Sensor Based on Surface Plasmon Resonance

“…Surface Plasmon Resonance (SPR) is defined as an optical phenomenon that occurs when p-polarized light excites a charge density oscillation at the metal-dielectric interface by achieving the phase-matching state between the p-polarized light and SP [5][6][7][8][9]. Combining the advantages of PCF technology with plasmonic science, PCF-SPR sensors have been developed for a wide range of potential applications such as water testing [10], food safety, solution concentration measurement [11], environmental monitoring, biochemistry research [12], gas detection, medical diagnostics, and so on [13].…”

Estimating concentration of toxic ions Arsenic in water by using Photonic Crystal Fiber based on Surface Plasmon Resonance (SPR)

“…This technology is extensively used as a detecting foundation for many sensors in a number of fields, such as gas sensing, chemical detection, and bio detection 10,11 . Surface Plasmon Resonance, also known as SPR, is an optical phenomenon that happens when light induces a charge density oscillation at the metal dielectric interface by attaining the phase-matching condition between the polarized light and SP [12][13][14][15] . PCF-SPR sensors have been created by the integration of plasmatic science and the benefits of photonic crystal fiber technology, and they offer a wide variety of possible uses, including water monitoring 16 , environmental surveillance, biochemistry study 17 , medical diagnostics, gas detection, and so forth 18 .…”
