  • 高非线性高双折射光子晶体光纤是超连续谱产生的最有效介质之一, 因此本文选取V型光子晶体光纤作为研究对象. 通过多极理论数值模拟的结果, 确定V型光纤具有高双折射、高非线性等特性. 通过实验手段, 发现入射光中心波长和光纤的双折射效应对产生的超连续谱有很大的影响: 当入射光波长处于光子晶体光纤大的反常色散区时, 脉冲相对展得比较宽, 长轴要比短轴方向的超连续谱更宽, 频谱成分更加丰富. 在同一波长下光偏振方向越接近45°时, 超连续谱谱宽范围越大. 随着入射脉冲功率的增加, 超连续谱展得越宽, 但是当功率比较大时会达到功率饱和.
    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.
