Microstructured optical fibers (MOFs) with small hole-to-hole spacing and large airholes are designed to compensate the anomalous dispersion and the dispersion slope of single-mode fibers. The geometrical parameters that characterize triangular MOFs are chosen to optimize the fiber length and the compensation over a wide wavelength range. A proper design of the photonic crystal fiber geometry allows us to achieve dispersion values of approximately -1700 ps nm(-1) km(-1) at 1550 nm and to compensate the dispersion of standard fibers within +/- 0.5 ps nm(-1) km(-1) over a 100-nm range. The MOF dispersion properties have been studied by means of a numerical simulator for modal analysis based on the finite-element method.
设计了具有小孔间距和大空气孔的微结构光纤（MOF），以补偿单模光纤的反常色散和色散斜率。选择表征三角形MOF的几何参数，以优化光纤长度和在宽波长范围内的补偿。光子晶体光纤几何结构的适当设计使我们能够在1550nm处实现约-1700ps nm（-1）km（-1）的色散值，并在100nm范围内将标准光纤的色散补偿到+/-0.5ps nm（-1）km（-1）以内。通过基于有限元法的模态分析数值模拟器研究了MOF的色散特性。
