摘要 利用平面波展开法,系统地研究了一种具有混合纤芯结构的光子晶体光纤的色散特性.数值计算结果表明,通过优化结构参量,这种新型结构的光子晶体光纤在通信窗口1.55μm附近可以获得带宽超过800nm的超平坦色散区域(色散曲线的变化范围不超过±0.6ps·km^(-1)·nm^(-1)). The dispersion properties of photonic crystal fibers (PCFs) with hybrid cores were systematically investigated by using plane-wave expansion method, The numerical calculation results show that an ultraflattened dispersion range of more than 800 nm in which the variation of dispersion is less than ±0. 6 ps · km ^-1· nm^-1 can be achieved at - 1.55 μm by properly designing the structure parameters of the PCFs.
