Abstract :
A simple technique for measuring optical fibre dispersion (or pulse spectrum if fibre dispersion is known) is demonstrated. Ultra-short pulses are linearly dispersed in the fibre under test, thus mapping their spectrum to the time domain. The delay between two spikes in the dispersed pulse´s temporal profile, corresponding to two spectral spikes, accurately gives the dispersion
