Pulse Propagation in Single-Mode Fibers Part 2

Apart from chirped Gaussian pulses it is difficult to obtain, for other shapes of pulses, closed-form analytical expressions for pulse propagation along optical fibers. What is feasible, however, it to calculate the root-mean-square width of arbitrary-shaped pulses.
