Transmission bandwidth properties of GeO(2)-P(2)O(5)-doped silica graded-index optical fibers.
Transmission bandwidth properties of GeO(2)-P(2)O(5)-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 alpha on the vertical axis and wavelength lambda horizontally. The material dispersion sigma(m)(lambda) and the optimal profile parameter alpha(opt)(lambda) 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 lambda = 0.82,1.06,1.27, and 1.52 microm for twenty GeO(2)-P(2)O(5)-doped silica graded-index fibers with different alpha values.
