Abstract

A temperature-sensor is presented based on the solid core photonic crystal fiber (PCF) infiltrated with the magnetic fluid (MF) in all or some parts of the cladding air holes with the help of the syringe injection technique. The 8.5-cm length of the proposed PCF sensor is used. A Mach–Zehnder interferometer modal is used for the detection process. The applied temperature is given in a range from 25.6°C to 100.1°C. The calculated outcome justifies that a very clear interference spectrum is obtained between the change of the refractive index of the MF and the temperature. From the experimental outputs, the temperature sensitivity of the intended PCF is −0.38 nm / ° C, and at high temperature, it achieves 0.176 nm / ° C. The MF has great sensitivity at high temperature. This proposed sensing system may find potential applications in medical science and industry.
