title: Direct measurement of self-phase shift due to fiber nonlinearity.
abstract: We directly measure the time-independent nonlinear self-phase shift of a pulse after fiber propagation by spectral interferometry. Both the soliton and the nonsoliton case were studied. We verify numerically that the measured phase shift approximates this time-independent phase well.
