Photonic Crystal Fiber-based Temperature Sensor

Abstract

This work reports a unique photonic crystal based temperature sensor. The modal analysis of photonic crystal fiber structure for the electric field distribution has been presented for X-polarization and Y-polarization. The coorelation analysis between the effective mode index and temperature has been investigated in the sensor using Comsol Multiphysics. The proposed sensor presents the the variation of temperature in the range of 20 degrees to 100 degree celcius which shows the variation of effective of mode index 1.273 to 1.276. The design includes the effective use of C2H5OH (ethyl alcohol or ethanol) as a analyzing medium for the sensing of temperature. The device present the fundamental concept of temperature sensing using photonic crystal fiber which can be employed for the further utilization in complex circuits for various application in Biophotonics, integrated optics etc.
