Abstract

Detection of liquid mixture of different volume ratio is very important in industrial purposes. The paper reports a sensing mechanism of binary liquid mixture for different volume fraction, based on the measurement of refractive index of the mixture. Here, a highly sensitive liquid filled core Photonic Crystal Fiber structure has been proposed to detect liquid mixture solution. Numerical investigation of the proposed structure is carried out by employing full vectorial Finite Element Method (FEM).

Highlights

  • Fiber optic technology was developed primarily for telecommunication and medical science

  • The proposed Photonic Crystal Fiber (PCF) structure has a liquid filled hollow core which operates in the near-infrared region (NIR)

  • This paper reports a framework for binary liquid mixture sensing application using the theoretical mixing rules

Summary

Introduction

Fiber optic technology was developed primarily for telecommunication and medical science. The recent advances of fiber optic technology with its widespread of applications lead extensive interests to the researchers. The emergence of Photonic Crystal Fiber (PCF) was a breakthrough in the fiber optic technology. Since the invention of PCF using 2D photonic crystal, in 1992 [1], the fiber optic researchers have been engaged on Research and Development (R & D) with this type of fiber.
