Abstract :
The temperature sensitivity of a two-mode (TM) photonic crystal fiber (PCF) interferometric sensor was investigated theoretically and experimentally. In contrast to the conventional elliptical core TM fiber interferometric sensors, the temperature sensitivity of the PCF sensor has a nonmonotonic dependence on the operating wavelength, and was measured to be 0.083, 0.147, and 0.136 rad/degCmiddotm at 543, 975, and 1310 nm, respectively
