Abstract: High nonlinear and high birefringent photonic crystal fiber is one of the most effective medium for supercontinuum generation, therefore we select the V-type photonic crystal fiber as the research object. Through the numerical simulation results of multipole theory, we determined that the V-type optical fiber has high birefringent and high nonlinear characteristics. Through experiments, we found that the birefringence of the fiber and the central wavelength of the incident light have great influence on the generation of supercontinuum: when the central wavelength of incident light in the anomalous dispersion region of the fiber, its spectrum is quite wide relatively, and the supercontinuum of the long axis is flat tar than that of the short exis and has more abundant spectral components; at the same wavelength of light, the polarization direction of the former is closer to 45°, the supercontinuum spectrum range is larger. With the increase of the incident pulse power, supercontinuum will spread wider, but will reach a saturation when the power is large enough.
