Coherent information storage with photon echoes produced by switching electric fields

We demonstrate modified photon echoes in Eu3+:Y2SiO5 by controlling the inhomogeneous broadening of the F-7(0) *<-> D-5(0) optical transition in Eu3+. These modified photon echoes are shown to be capable of storing phase and amplitude modulation. (C) 2007 Published by Elsevier B.V.
