Design of a Mono-Rectangular Cored Symmetrical PCF Structure for Sensing Differently Concentrated Glucose Solutions in THz Regime

Abstract

This research illustrates a simple mono-rectangular cored symmetrical PCF (MRC-SPCF) sensor that is used for detecting different concentrated glucose samples (from 0% to 60%). The simulations are carried out within 1-2 THz regimes based on the principles of the finite element method (FEM). After a completed investigation we have found the values of a range of optical properties that are comparable to the previously published results. From our investigation, we found 94.43% relative sensitivity with a negligible effective material loss (EML) of 0.004 cm-1 at 1.8 THz respectively for 60% and 20% concentrated glucose solution. Besides this proposed MRC-SPCF sensor also expresses almost zero confinement losses for all the glucose samples within the operated frequency range. Hence we can admire that this proposed MRC-SPCF sensor can be a potential aspirant in chemical sensing which can make an impact both in the medical and industrial sectors.
