Abstract :
A narrow pulsed Gaussian beam of wavelength between 1.06 ¿m and 1.6 ¿m is used to excite selectively a graded-index fibre in order to measure the spectral behaviour of the resulting pulse delay. This measurement demonstrates the excitation-dependent material dispersion in multimode fibres. Comparisons of experimental results with calculations based on certain published bulk material data show reasonable agreement.
