设计了一种高双折射高非线性多零色散波长的全内反射光子晶体光纤,采用有限元法研究了这种光纤的有效模面积、非线性、色散和双折射特性. 计算结果表明,通过设置合适的结构参数,该光纤可在波长1.55 μm处获得2.54×10-2的双折射,也可在X,Y偏振方向分别获得50.22 W-1·km-1和54.61 W-1·km-1的高非线性系数. 另外,该光纤在近红外波段出现了两个零色散波长,其中的一个零色散波长出现在1.55 μm附近. 本设计为获得高双折射高非线性多零色散波长的光子晶体光纤提供了一种新的结构,其在偏振控制、非线性光学、色散管理和超连续谱传输方面具有广泛的应用前景.A novel kind of total internal reflection photonic crystal fiber (TIR-PCF) with highly nonlinear, large birefringence and multiple zero-dispersion wavelengths is designed. Characteristics such as birefringence, effective mode areas, nonlinearity and dispersion are investigated by finite element method (FEM). Numerical results demonstrate that the birefringence is 2.54×10-2 at the wavelength of 1.55 μm, and high nonlinear coefficients (50.22 W-1·km-1 and 54.61 W-1·km-1 in X, Y polarization directions respectively) are obtained by setting the appropriate structure parameters. In addition, two zero-dispersion wavelength points appear in the infrared band, one of which emerges near the wavelength of 1.55 μm. The design provides a new structure for large birefringence, highly nonlinear and photonic crystal fiber with multiple zero-dispersion wavelengths, and it could be widely used in polarization control, nonlinear optics, dispersion management and super-continuum generation.
