Review of Optical Data Storage,cording/reading speed. However, we have reached the point where a substantial increase in the capacity cannot be produced without increasing the size of the system. When compact discs (CDs) were introduced in the 1980s they revolutionized the concept of data storage. Since their inception, the capac

Two-Step Processes and IR Recording in Photorefractive Crystals,th red or near—IR light and nondestructive readout of information is possible. Often shallow levels are involved in the holographic recording process in photorefractive crystals. The shallow levels can be populated by illumination with visible or UV pulses forming states with relatively long lifetim

Gated optical holographic recording allows us to obtain high-diffraction efficiencies in the near InfraRed (IR) jointly with long-term storage. In particular, the roles of stoichiometry and dopant reduction state in LiNbO. in the optimization
