The optical dispersion in singly clad dielectric monomode waveguides is calculated by taking into account the frequency dependence of the refractive indices of the core and the cladding materials. The total dispersion is composed of the material dispersion and the dispersion of the waveguide structure. Fibers can be optimized in such a way that these two portions have opposite signs. The portion due to material dispersion, however, is about 2 orders of magnitude greater than that due to waveguide structure dispersion (considering typical glasses at wavelengths of 0.9 microm and 1.06 microm). Thus, complete compensation of these portions is impossible, and the fibers cannot be made dispersion-free at these wavelengths. The total dispersion at 1.06 microm, however, is smaller than at 0.9 microm by a factor of ?
通过考虑纤芯和包层材料折射率的频率依赖性，计算了单包层介质单模波导中的光色散。总色散由材料色散和波导结构色散组成。可以通过优化光纤，使这两部分具有相反的符号。然而，材料色散部分比波导结构色散部分大约大2个数量级（考虑波长为0.9微米和1.06微米的典型玻璃）。因此，不可能完全补偿这些部分，并且在这些波长下无法使光纤实现无色散。然而，1.06微米处的总色散比0.9微米处小多少倍呢？
