Simultaneous Sensing of Dual Analyte 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 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.
