Abstract
The variation of the core-cladding refractive index difference Δn(λ) is determined as a function of wavelength for GeO2-SiO2, B2O3-SiO2, TiO2-SiO2, P2O5-SiO2, Al2O3-SiO2, and Cs2O-SiO2 optical fibers. The measurements are obtained by electronically processing the output of an interference microscope illuminated by a monochromatic light source variable over the 0.5–1.1-µm range. The Δn(λ) results are utilized to calculate the precise grading of the refractive index profile characterized by an exponent α(λ) required to achieve a minimum modal dispersion. The material dispersion for these compositions is also calculated with the aid of available n(λ) data for SiO2.
