    Abstract

    We numerically demonstrate that adaptive pulse shaping can deliver ultrashort pulses arbitrarily shaped in both amplitude and phase through a single-mode optical fiber. For quick evaluation of the amplitude and phase of shaped pulses during iterative optimization, two-dimensional patterns obtained from frequency-resolved optical gating (FROG) measurement are used without pulse reconstruction. By controlling only the spectral phase of the input pulse before the fiber propagation to compensate the group delay dispersion and self-phase modulation, various desired pulse shapes can be generated at the fiber output. However, this scheme is limited to use with moderate peak powers.
