Total internal reflection(TIR) photonic crystal fiber(PCF) has been studied through analyses of its mode,dispersion,polarization and nonlinearity.For analysing the dispersive behavior of TIR-PCF at short wavelength region,we employ the concepts of effective refractive index and effective normalized frequency for the first time.In this way,the very dispersive property of blueshifted zero-GVD wavelength is explained successively.We also demonstrate the application value of this type of fiber through practical examples.
