Abstract

We demonstrate a high temperature sensor by using an intrinsic photonic crystal fiber (PCF) based Mach-Zehnder interferometer. Air hole collapsed regions inside the PCF act as coupler between the core and cladding modes which form the two arms of the interferometer. The temperature measurements are obtained by measuring the shift in the peaks of the interference signal. The experiments confirm the reliability, repeatability and hysteresis. The small amount of hysteresis and deviation in the repeated experiments are within the experimental errors.
