Design and Computational Analysis of Dual Core Photonic Crystal Fiber Temperature Sensor based on Surface Plasmon Resonance

Abstract

This paper present dual core photonic crystal fiber temperature sensor in terms of wavelength sensitivity. The high temperature coefficient liquid and plasmonic material are deposited outer layer of the PCF to make the fabrication easier than existed optical sensor. Besides, the coupling phenomenon is studied. The Matlab environment as well as the finite element method (FEM) are used to demonstrate the sensor performance. Different loss spectra with the variation of temperature has been analyzed. The simulation result shows that the proposed sensor exhibits wavelength sensitivity of 970 pm/°C and 1075 pm/°C for x-polarized light and y-polarized light respectively. Moreover, a wide range of temperature 0°C to 80°C can be detected effectively. Considering high sensitivity and wide detection range of temperature, this dual core PCF temperature sensor can be a promising candidate for the detection of the temperature of manufacturing industry, medical environment and various applications.
