Abstract
Transmission bandwidth properties of GeO2-P2O5-doped silica graded-index fibers have been investigated. Theoretical results obtained from Olshansky’s theory are represented in the form of a bandwidth map with profile parameter α on the vertical axis and wavelength λ horizontally. The material dispersion σm(λ) and the optimal profile parameter αopt(λ) determined by the glass refractive-index measurement are used for calculating the transmission bandwidth. It is confirmed that the estimated results from the bandwidth map agree with the experimental results of transmission bandwidth measurements at λ = 0.82, 1.06, 1.27, and 1.52 μm for twenty GeO2-P2O5-doped silica graded-index fibers with different α values.
