It is proposed that the concentration profiles of the components of a multicomponent glass be specified independently in order to synthesize an optical fiber having several optimized transmission characteristics. Assuming a linear relationship between concentration and refractive index, we show how the synthesis procedure operates for ternary glasses and illustrate the method by computing the concentration profiles required to realize a SiO(2)-GeO(2)-P(2)O(5) fiber with minimum modal dispersion over a wide range of wavelengths ( partial differentialalpha/ partial differentiallambda = 0).
为了合成具有多种优化传输特性的光纤，建议独立指定多组分玻璃各组分的浓度分布。假设浓度与折射率之间存在线性关系，我们展示了三元玻璃的合成过程是如何操作的，并通过计算在很宽的波长范围内实现具有最小模间色散（∂α/∂λ = 0）的SiO₂-GeO₂-P₂O₅光纤所需的浓度分布来说明该方法。
