Abstract
A method of ultrafast switching of ferroelectric polarization is suggested. The method is based on the interaction of a ferroelectric sample with the feedback field of a resonator in which the sample is inserted. The polarization reversal time can be of order of femtoseconds. The polarization switching produces a coherent electromagnetic pulse.
