摘要: The variation of the core-cladding refractive index difference Deltan(lambda) is determined as a function wavelength for GeO(2)-SiO(2), B(2)O(3)-SiO(2), TiO(2)-SiO(2), P(2)O(5)-SiO(2), Al(2)O(3)-SiO(2), and Cs(2)O-SiO(2) optical fibers. measurements are obtained by electronically processing output an interference microscope illuminated monochromatic light source variable over 0.5-1.1-microm range. results utilized to calculate precise grading profile characterized exponent alpha(lambda) required achieve minimum modal dispersion. material dispersion these compositions also calculated with aid available n(lambda) data SiO(2).
