A novel technique for obtaining the amplitude and phase of optical pulses with time extents as short as tens of ps is presented. The method which is based on a property of the Wigner Distribution Function (WDF) only requires, for a practical realization, of passive optical communication components. It employs as the main component a dispersive element with a known dispersion coefficient. Two different setup implementations are considered, for which simulations are carried out in order to test the method performance taking into account both, realizable models of the involved devices and typical pulses found in optical transmission systems. This numerical analysis shows the practical feasibility, range of operation and the limitations imposed by the mismatch and/or variation of the device parameters.
