Simultaneous Sensing of Dual Analyte with Photonic Crystal Fiber Based Liquid Sensor

Abstract

This article proposes three novel models of photonic crystal fiber (PCF) based dual liquid sensor. The performances of Z-Model, X-Model, and V-Model structures have been evaluated by applying the well-known full vectorial finite element method (FV-FEM) where boundaries are defined with perfectly matched layers (PMLs). The proposed models have been investigated with two types of analyte arrangements (A-Type and B- Type) in the core region. The birefringence and the sensitivity levels of proposed sensors have been studied where core holes are filled with water (n=1.33) and ethanol (n= 1.354). Our numerical results have shown that X-Model and Z-Model of A-Type sensor is an ideal structure for water and ethanol sensing, respectively.
