Problem 1.4 Nonlinear Optics, Agrawal

A 1-km long single mode fiber with zero-dispersion wavelength at 1.4um is measured to have D = 10 ps/km-nm at 1.55um. Two pulses from Nd:YAG lasers operating at 1.06 and 1.32um are launched simultaneously into the fiber. Calculate the delay in the arrival time of the two pulses at the fiber output assuming Beta_2 varies linearly with wavelength over the range 1.0-1.6um.
