Abstract

Holographic data storage offers various advantages, such as high storage density and rapid transfer rates, and short access time. An essential criterion for this method to be practical is the ability to retain information after many readout cycles. Several fixing techniques have been investigated,1 including thermal fixing, electric fixing, two-photon recording; and multiple species participating in grating formation in photorefractive crystals.9,10 Signs of possible nonvolatile readout involving two species forming complementary gratings have been observed in Bi2SiO20,2 BaTiO3,3 and LiNbO3:Cu and Fe.4,5
