Broadening of Intensity-Modulated Pulses in Single-Mode Fibres (Invited Paper)

The main state-of-the-art techniques for the evaluation of chromatic dispersion in single-mode fibres are reviewed, and methods based on nearfield, farfield, and/or spot-size measurements are mentioned. A mathematical development for the estimation of pulse shapes (for arbitrary input pulses) is presented together with an analytical formula for the Gaussian pulse case.
