Profile synthesis in multicomponent glass optical fibers.

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).
