Abstract
We measure a value of N-2 = 2.45 x 10(-16) cm(2)/W (+/-5%) by self-pha se modulation (SPM) in two 20 km dispersion-shifted fibers for random polarization at 1.55 mu m. There is still some dispersive broadening a nd we find that an accurate determination of N-2 requires fitting the experimental (SPM) spectra with a computer simulation to account for t he variation in pulse shape and fiber properties along the length of t he fiber. We also show that spectral information provides information about the input pulse properties.
