摘　　要：A kind of double-cladding photonic crystal fiber （DC-PCF） with high birefringence and two zero-dispersion wavelengths is proposed. It is found that the birefringence of DC-PCF with inner cladding air holes pitch 1.0μm and diameter 0.8μm is 1.001×10-2 in the optical communication band at wavelength 1.55μm by the multipole method. It is demonstrated that two zero dispersion wavelengths can be achieved in the optical communication band between 0.8μm and 1.7μm, and the first zero-dispersion wavelength is in the working wave band of the Ti：sapphire oscillator, which contributes to the frequency conversion of the Ti：sapphire femtosecond laser. PCF with two zero-dispersion wavelengths can make strong power supercontinuum spectral in the near infrared band.A kind of double-cladding photonic crystal fiber （DC-PCF） with high birefringence and two zero-dispersion wavelengths is proposed.
