Frequency-resolved optical gating is used to characterize ultrashort optical pulses that are compressed nonadiabatically in dispersion-decreasing fiber. The pulses undergo an interesting temporal pulse breakup following dispersion in both the normal and anomalous regimes, and compression ratios close to the adiabatic limit are obtained. All behaviors are in excellent agreement with numerical integration of the nonlinear Schrödinger equation.
