Holographic storage experiments using crystal Sr_0. 75Ba_0. 25Nb_2O_6 (SBN 75/25) as a
volume-phase holographic medium show that this material is the most sensitive crystalline …

High optical sensitivity is observed in 0.1 wt% Ce‐doped strontium barium niobate (SBN)
crystals in the absence of an external electric field. Only 5–10 mJ/cm2 of incident 0.488‐μm …

Single‐crystal Sr0. 75Ba0. 25Nb2O6 when used in conjunction with an externally applied
electric field is shown to be a sensitive volume holographic medium capable of high …

A read-and-write, randomly accessible, multilayered optical memory with a Bi_12SiO_20
crystal as the medium is demonstrated. Data are recorded in the crystal as an absorption …

We describe a novel procedure for obtaining enhanced nondestructive holographic readout
in SBN, where the key new ingredient is utilization of degrees of freedom in polarization of …

This paper describes recent improvements in materials and techniques for storage of high
efficiency phase holograms in electrooptic crystals. The storage performance of lithium …

Volume phase holograms are holograms stored throughout a material whose thickness is
much greater than the wavelength of light. This paper is a review of the present state of the …

80 100 120 140 TlME (sec) were then removed from the solidified melt. Chemical analysis of
the crystals showed O. 036-wt% Fe and 0.002-wt% Mo. The sample used for the tests was …

Shift invariance in the context of associative memories is discussed. Two optical systems
that exhibit shift invariance are described in detail with attention given to the analysis of …

The potential of high‐speed optical memories using electro‐optic or acousto‐optic light
deflection for address selection is examined. It is shown that for such memories the total …
