In this paper, the affection of the effective index and normalized frequency with the temperature have researched based on filling methanol in photonics crystal fiber with the hexagon structure. The theoretical model of the total internal reflection photonics crystal fiber has studied on plane-wave expansion technique. The results of the total internal reflection photonic crystal fiber (TIR-PCF) temperature characteristics have obtained in filling the high refractive index temperature coefficient liquid material. The refractive index of filling liquid and temperature affect on the effective refractive index and normalized frequency. The effective refractive index will reduce and normalized frequency will increase as the temperature increases. When the distance between adjacent holes Λ remains unchanged, the ratio of diameter of holes d and Λ of d/Λ is greater and the input wavelength is longer, the effective refractive index with the temperature becomes the most sensitively. The properties are valuable for design and application of temperature sensors.
