3、HebeiUniversity, Baoding071002, China)Abstract: The basic structure, guiding principle and the characteristics of the photonic crystal fiberwere introduced briefly.According to theprinciple of sensing, photonic crystal fiber sensors aredivided into fourkinds: theabsorbablephotonic crystal finullber
4、sensors, the fluorescent photonic crystal fiber sensor, the interferential photonic crystal fiber sensors and the photonic crystalfibergratings sensor. Themechanism, structure, characteristics and the progress of these photonic crystal fiber sensors were disnullcussed respectively.Keywords: photonic
