In this paper, a high sensitivity temperature sensor based on photonic crystal fiber long period grating (PCF-LPG) filled with ethanol is proposed and simulated by full vector finite element method. The relationship between the resonant wavelength shift, and the temperature was analyzed. The results show that the resonant wavelength of the ethanol filled photonic crystal fiber long period grating is proportional linearly with temperature and the highest  sensitivity of  was achieved, which is 90 times higher than that of conventional LPG temperature sensors.
