Abstract

We demonstrate photon echoes in Eu3:Y2SiO5 by controlling the inhomogeneous broadening of the Eu3+F07↔D05 optical transition. This transition has a linear Stark shift, and we induce inhomogeneous broadening by applying an external electric field gradient. After optical excitation, reversing the polarity of the field rephases the ensemble, resulting in a photon echo. This is the first demonstration of such a photon echo, and its application as a quantum memory is discussed.
