摘　　要：提出了一种新型结构的光子晶体光纤(PCF),利用全矢量有限元方法对其色散和非线性特性进行了数值分析。通过优化结构参数,得到了三种在不同波段具有较高非线性的近零色散平坦、宽带色散平坦甚至色散超平坦的光子晶体光纤,并给出了这种微结构PCF预制棒的制备方法。这些新型光纤在全光格式转化、超连续谱产生、光波长转换等领域具有良好的应用前景。A novel structure of photonic crystal fiber （PCF） is proposed ,and the dispersion and nonlinear properties of the PCF are analyzed numerically based on ful] vector finite element method. Three PCFs with high linearity and nearly-zero flattened dispersion or broadband flattened even ultra-flattened dispersion in different wave bands are obtained by optimizing the structure parameters, and the method is presented to fabricate the microstructured fiber preform as well. These novel PCFs proposed have bright prospects of applications in all-optical format conversion, super-continuum generation and optical wavelength conversion,and other fields.
