Paper Abstract

We propose a photonic crystal fiber (PCF) temperature sensor that is based on intensity modulation by magnetic fluid (MF) filling of air holes with index-guiding PCF. Temperature characteristic of MF-filled PCF is investigated without magnetic field and with weak magnetic field. The results show that light is still guided by total internal reflection (TIR) in this device because MF has a smaller refractive index than the material in the fiber core; the transmission power of the MF-filled PCF is used as the sensor signal to investigate its temperature properties. The temperature sensitivity of transmission power was experimentally determined to be 0.06dBm/oC for a 10cm-long PCF without applying magnetic field.
